We’ve seen the 100-400mm f/5-6.3 DG DN OS Contemporary before because it’s the current full-frame super-telephoto option from Sigma for mirrorless cameras. What we haven’t seen before is a full-frame Sigma that has been specifically adapted for the APS-C-sized Fujifilm lens mount — until now.
At first glance, you might be thinking that a full-frame lens is going to be excessively large and bulky in front of an APS-C-sized sensor. What about all that extra light designed to cover a much larger sensor being wasted on Fujifilm bodies? Is the Sigma 100-400mm f/5-6.3 DG DN OS a feasible option or a ridiculous mash-up?
Sigma 100-400mm f/5-6.3 DG DN OS Contemporary: Handling
Fujifilm already makes a 100-400mm with a slightly faster f/4.5-5.6 maximum aperture. It’s a fairly heavy lens despite being made specifically for APS-C at 48.5 ounces (1,375 grams). It’s also fairly bulky in the hand and has a similar intention to the Sigma, with its built-in optical stabilization and identical focal range.
Despite the Sigma 100-400mm being designed for full-frame, it actually comes in significantly lighter at just under 39 ounces (1,100 grams). Although a similar size, I found the Sigma to be well-balanced and agile in hand.
Physically, the Sigma 100-400mm has a smooth zoom ring that can be locked to prevent barrel creep. It’s a weather-sealed design and like all Sigma Contemporary lenses, feels well-built and solid. There is the usual telephoto lens setup with an AF selector switch, focus limiter, customizable control button, and image stabilizer controls. The hood clicks on with a positive locking action and there is a lens collar available to balance the weight on a tripod. However, Sigma does not provide the lens collar out of the box and you’re going to want it, so factor in that extra cost.
Sigma 100-400mm f/5-6.3 DG DN OS Contemporary: In The Field
With the 100-400mm, the first thing I tried was close-up photography. It is a challenging affair with the large working distance of roughly 1.5 meters away, but you definitely won’t spook the insects. I got some great shots of butterflies and insects with the 1:4 macro reproduction and the optical stabilization helped my success rate.
When shooting toward the sun or bright light sources I found the flare resistance of this lens to be pretty average. Some loss of contrast was present and the lens displays some obtrusive green ghosting when stopped down. But, generally speaking, long telephotos don’t often involve the sun or light sources directly in the frame and the supplied lens hood does a good job of cutting out flare in most situations.
When it comes to bokeh and the rendering of out-of-focus areas I found the Sigma 100-400mm to have some very minor cat’s eye effect shooting wide open. Stopped down, the highlights are nice and round although they do exhibit significant soap-bubble effects and onion rings, too. Fortunately, the look of out-of-focus backgrounds was quite nice. You are going to see a lot of soft backgrounds when shooting wildlife and it’s important that the lens renders them to your liking. The Sigma backgrounds don’t look overly harsh and transitions from sharp areas look pleasing.
Sigma 100-400mm f/5-6.3 DG DN OS Contemporary: Sharpness is Key
The first thing I want to get across is that detail-robbing diffraction is always present with any camera system and that the more you stop your lens down the softer things get. Of course, stopping down does improve the appearance of some optical aberrations and brings more of your image into focus. Eventually, you will find that the softness from diffraction outweighs any benefits to stopping down, and thus — in incredibly simplified terms — we don’t want to go much past f/8 or f/11 if we don’t have to. Long story short, you don’t have much aperture range to play with on a slower lens like this.
At 100mm I found the Sigma to be very sharp shooting at f/5 both at the center and corner of the image. Stopping down to f/8 gave a noticeable improvement in both contrast and detail. At 400mm it was an identical story, with f/6.3 giving great results and f/8 improving things even further. I’d happily shoot wide-open throughout the focal range but stopping down does help a little. If you absolutely need the depth-of-field you can stop down further but you’ll be losing some overall detail pretty quickly.
Regardless, I was impressed with how good the corners were on this lens because the APS-C Fujifilm sensor only uses the light from the more central “sweet spot” of the full-frame image circle projected into the camera. This certainly isn’t a bright lens though, and I often had to use a higher ISO than I would normally want to. I would factor in how much low-light shooting you’ll do, and how willing you are to compromise some image quality in those situations compared to a faster, but more expensive lens.
Sigma 100-400mm f/5-6.3 DG DN OS Contemporary: A Full-Frame Compromise
At first, I assumed that a full-frame lens on a smaller Fujifilm body would be a poor stop-gap measure for Sigma until it could make a novel lens purpose-built for the X-Mount. In truth, the alternatives are sparse which makes it a lot easier to recommend. The Fujifilm XF 100-400mm is a great lens but it’s larger, heavier, and only marginally brighter. It’s also dramatically more expensive.
The Sigma 100-400mm is not a bright lens by any stretch and there is some compromise there, yet it provides some excellent sharpness and good overall optical performance without breaking the bank, or the arms. It may be a stop-gap after all but it’s a worthy one for the prospective wildlife or action shooter on a budget since it costs just $949.
Are There Alternatives?
The aforementioned Fujifilm XF 100-400mm f/4.5-5.6 is a solid choice, with a hefty $1,899 price. Its linear autofocus motors are definitely faster and might be worth it in demanding situations.
You could also go with the even more affordable Fujifilm XF 75-300mm f/4-5.6 but you’ll give up significant reach at the long end.
Should You Buy It?
Yes. The Fujifilm X system lacks a range of telephoto zooms. Any additional options are welcome and the Sigma delivers good images.


I just received this from Mike Williams, who would have ever thunk it
While helmets aren’t required in many states to ride a motorcycle on the streets, a huge number of riders do choose to wear a helmet to help protect them in the event of an accident. One of the complaints of wearing a helmet is that it limits some of your vision and makes it more difficult to see what’s going on behind you. A company called Reevu has a helmet that has the world’s first rear view imaging system built right in.
The helmet is called the RV MSX1 Motorcycle helmet and has a flip up front. The helmet will be ready for the 2013 riding season and has been tested and approved to DOT standard for the US and ECE 22.05 standards for European markets. The helmet has an integrated optical device that allows motorcyclists to view the road behind them through the helmet.
At first glance you might think that the helmet uses a camera system, but it doesn’t. The optical device that shows the rider what’s behind them uses a number of reflective surfaces that are coated onto a bullet proof material. The optical device bends light over the top of the wearer’s head allowing them to see what’s behind them using their peripheral vision.
The company already has a standard full face model planned (pictured) called the RV FSX1 that will launch later this year. The helmet offers motorcyclists a rearview mirror system. The optic system can be moved to adjust the rearview to suit the rider’s needs. The reflective polycarbonate plate used in rearview system also act as a crumple zone in the event of an accident helping to protect the rider even further.

04/05/2023- Middlesex, NJ: Whether you’re in the military yourself and looking for a pair of military sunglasses, or you simply want to get that enhanced level of ballistic level of protection, Wiley X safety glasses can, at times, come with those military specifications. Wiley X military glasses are designed to be built for the harshest and most hazardous environments out there in the world. That means that Wiley X military sunglasses provide enhanced protection and focus on continuous comfort and the clearest vision possible at all times.
That’s why any Wiley X military options carried by RX-Safety come with not just ANSI Z87 ratings but also evolving military safety standards that go beyond just the frames and lenses but the overall quality of the whole package. So let’s look at these Wiley X safety sunglasses options.
Wiley X Saber
The first pair of military glasses we’ll take a look at is the Wiley X Saber. These are extremely lightweight, semi-rimless in design, and come with an adjustable nose piece and a foam insert for maximum comfort. The Wiley X Saber is also extremely versatile since it comes with interchangeable lenses on the same frame.
These T-Shell™ lenses also come with 100% UVA / UVB protection and additional coatings against scratches. They are also quite tough, made from Polycarbonate material known as their Shatterproof Selenite™. The Wiley X Saber quickly becomes Wiley x prescription safety glasses with the possibility of getting prescription inserts.
They also meet all standards for ANSI Z87.1 as well as MIL-PRF-32432(GL) ballistic ratings. The frame itself is matte black with pale yellow, clear, light rust, and smoke gray as your lens color options.
Wiley X Romer 3
These have the Wrapback™ feature, which helps to support the peripheral vision that’s also protected. You’ll also see crisper colors with its Light transmission being at 89% when using the non-clear lens color options.
Again, versatility is important with Wiley X Military glasses. You can switch out the lenses here that also come with the T-Shell™ anti-scratch coating and 100% UVA / UVB protection. This makes them an excellent option for various indoor and outdoor lighting conditions, and they can easily adapt to the situation. These are ready to obtain a Wiley X prescription safety glass and come with ANSI Z87.1-2010 and MIL-PRF-32432 ratings. The Wiley X Romer 3 comes in a matte black frame color. Consider these also if you use night vision goggles.
Wiley X Spear
The final option we’ll look at is the Wiley X Spear, which are goggles, not Wiley X Safety glasses. However, they still meet MIL-PRF-32432 ballistic ratings as well as ANSI Z87.1 high velocity and high mass impact ratings.
The Wiley X Spear also keeps the theme of flexibility with interchangeable lenses that also come with the T-Shell ™ scratch-resistant coating. These lenses also come with Foil™ coating to prevent fog build-up. You can get these in smoke gray, clear, or light rust, with the ability to also get prescription inserts.
The goggles come in a tan color and also have an adjustable strap. These come compatible with night vision equipment as well.

OPPO unveils world's first periscope style '5x Dual Camera Zoom'
OPPO has unveiled '5x Dual Camera Zoom' – the world's first periscope-style dual-camera technology for smartphones at Mobile World Congress (MWC) 2017.
Sky Li, VP, OPPO, MD of International Mobile Business & President of OPPO India, said, “The ‘5x Dual Camera Zoom’ has opened up yet another realm of possibility in terms of smartphone photography, and is a reflection of our dedication to delivering on what our customers want and need - to take beautiful and clear pictures”.
The company has been working on this dual-camera technology for almost a year now, and has filed currently more than 50 patents for this technology.
Idea for this 5x Dual Camera Zoom was inspired from periscope used on submarines, it said.
OPPO said, "5x Dual Camera Zoom is the Optical Image Stabilisation (OIS) solution. Different from other manufacturers who use optical image stabilization on the wide-angle lens, the company took a new approach and applied OIS directly to the telephoto lens."
This technology will offer 5x lossless zoom capability on a smartphone, which will set the bar high compared to the 2x zoom functions available in the market presently.
5x dual camera module is only 5.7mm thick, which is even 10% thinner than a typical 2x optical zoom lens in a smartphone. Thus, it will help in keeping the smartphone thin.
It utilises wide-angle and telephoto lenses, and the housing for the telephoto lens uses an innovative periscope-style structure. By shifting the angle of the telephoto lens by 90 degrees, the lens will have the space it needs for a deep zoom.
While there is also a 3x optical zoom featured in this technology, matched with a proprietary image fusion technology for digital zoom, giving users the industry’s first-ever lossless 5x dual camera zoom.
Meanwhile, OIS solution can improve the performance of previous generations by 40%, and the prism mechanism dynamically adjusts its angle at precise increments of 0.0025o. This technology ensures that images are clear and stable even at full 5x zoom.
Sky Li added, “The dual cameras with wide-angled and telephoto lens, together with the periscope-style construction, our image fusion technology and the Optical Image Stabilisation, edges mobile photography even closer to what digital cameras are capable of doing."


Rayko Ivanov Stantchev and his team have found a way to look inside computer chips. With terahertz radiation, they are able to look through materials that are otherwise opaque.
Light, but not quite
Terahertz radiation is part of the electromagnetic spectrum. This spectrum also contains radio waves, ultraviolet rays and also visible light. All types of radiation are sorted by wavelength on the spectrum. Terahertz’s wavelength comes right between microwaves and infrared, making its wavelength slightly longer than that of light. This is excellent for looking through materials, because the longer the wave, the bigger the objects the wave can ‘see through’. That’s why your computer has no problem with seeing the WI-FI (that are in fact radio waves), that comes from your router, but you can’t see the router, if you’re not sitting next to it. Radio waves have a way longer wavelength, and thus they can ‘bend’ around your furniture, stairs and cat. While the visible light, that your eyes see, has a shorter wavelength and can’t bend around your cat. But in the ability of waves to bend around things also lays the problem. You don’t want the waves to bend around the thing that you actually want to see. Terahertz waves have just the right wavelength
|The electromagnetic spectrum, terahertz radiation comes between microwaves and infrared|
Looking straight through
With terahertz radiation, we can look through computer chips, while still being able to see the structures inside it. To be able to look inside the chip, Rayko Ivanov Stantchev and his team beamed patterns of radiation onto a slice of silicon, the material most computer chips are made out of, that was only a hundredth of a centimetre thick. Because of this pattern, the silicon become transparent for the terahertz radiation. But the structures inside the chip don’t become transparent, enabling the scientists to see them. With this technique, they were able to find malfunctioning parts in the chip as small as eight micrometres across. That’s about half as thick as the finest human hair.
|Image made with terahertz radiation,|
you can clearly see the structure
Computers and biology
The researchers consider using terahertz radiation a technique with much potential. For now, the possibility to see through silicon is limited by the thickness of the material, and the material can’t be really thick yet. Scientist predict that with improving the techniques, much thicker materials could be used. This can be really helpful with checking computer chips for malfunctioning parts, since the chips can just be ‘scanned’. But terahertz radiation has another interesting use. It could also be used in biology to scan tissues, because water, which is abundant in all living organisms, absorbs the terahertz radiation, making it easy to detect were there’s a lot of water. Because the radiation doesn’t bounce off of those spots. All in all a very promising technique that will benefit both computer sciences and biology.

Diamond Aircraft and Trakka Systems, a pioneer in advanced multispectral imaging solutions, recently collaborated on a successful demonstration of Trakka's new long-range TC-375 EO/IR imager integrated into a Diamond DA62 MPP aircraft. The week-long mission yielded exceptional results, showcasing the system's capabilities in Intelligence, Surveillance, Reconnaissance (ISR) and Search and Rescue (SAR) applications.
This collaboration builds upon a seven-year partnership between Diamond Aircraft and Trakka. Diamond Aircraft is renowned for its commitment to safety, performance, and efficiency and has served as both an integrator and an OEM for Trakka's advanced imaging systems. This successful demonstration further strengthens their collaborative efforts to push the boundaries of aerial technology.
The TC-375 EO/IR imager is a state-of-the-art multispectral imaging system that provides exceptional image clarity and situational awareness in diverse environments. This long-range and gyro-stabilized system features full HD (1080p) resolution for both integrated EO and IR sensors, enabling operators to obtain clear and highly detailed imagery in daylight, low light, complete darkness, and even in degraded atmospheric conditions such as fog, haze, and smoke.
The system features long-range optics that offer uninterrupted and continuous zoom, further improved by the next-generation image processing engine. This powerful combination provides two key advantages to users: maximum stand-off range and the ability to significantly enhance imagery. Additionally, users can blend the EO and IR channels to reveal hidden details at any distance.
"The mission tests with Diamond Aircraft were highly successful," said Adam Boniecki, European Sales Manager at Trakka Systems. "The TC-375 performed exceptionally well, delivering clear and actionable imagery for ISR and SAR operations. The TC-375's exceptional performance and ITAR-free single LRU design make it an ideal choice for the DA62 MPP platform. We are excited to continue collaborating with Diamond Aircraft and explore further collaboration in the future."

Scanning electron microscope image of initial prototype of light trapping 3D photovoltaic structures on a thin silicon wafer.
Solar3D, Inc., the developer of a breakthrough 3-dimensional solar cell technology to maximize the conversion of sunlight into electricity, today announced the successful fabrication and operation of a working 3-dimensional silicon solar cell that produces at least 250% of the power of a basic silicon solar cell.
Dr. Changwan Son, Solar3D’s Director of Technology, commented, “When measured relative to a conventional solar cell design, our working prototype produces electricity beyond our previous expectations. First, we fabricated our working prototype. Then we created a simple cell based on the conventional design, using the same fabrication environment, to serve as a control sample. By measuring the side-by-side power output of both cells, we were able to determine the relative performance under a number of conditions, ranging from bright sunlight to lower, diffuse light. In each test, our 3D Solar Cell consistently outperformed the control cell and produced at least 2½ times the amount of electricity under the same conditions.”
About 40 percent of the solar energy reaching Earth’s surface lies in the near-infrared region of the spectrum — energy that conventional silicon-based solar cells are unable to harness. But a new kind of all-carbon solar cell developed by MIT researchers could tap into that unused energy, opening up the possibility of combination solar cells — incorporating both traditional silicon-based cells and the new all-carbon cells — that could make use of almost the entire range of sunlight’s energy.
Solar power gathered in space could be set to provide the renewable energy of the future thanks to innovative research being carried out by engineers at the University of Strathclyde, Glasgow.
Researchers at the University have already tested equipment in space that would provide a platform for solar panels to collect the energy and allow it to be transferred back to earth through microwaves or lasers.
High-efficiency Alta Devices solar cell
To produce the maximum amount of energy, solar cells are designed to absorb as much light from the Sun as possible. Now researchers from the University of California, Berkeley, have suggested – and demonstrated – a counterintuitive concept: solar cells should be designed to be more like LEDs, able to emit light as well as absorb it. The Berkeley team will present its findings at the Conference on Lasers and Electro Optics (CLEO: 2012), to be held May 6-11 in San Jose, Calif.

Chennai: The Indian Space Research Organisation (ISRO) on Tuesday evening released a 3D images of Vikram Lander carried onboard the third lunar mission Chandrayaan-3, by Pragyan Rover on the moon’s surface. The image was captured on August 30. In an update, ISRO posted “Chandrayaan-3 Mission: Anaglyph is a simple visualization of the object or terrain in three dimensions from stereo or multi-view images.”
The Anaglyph presented here is created using NavCam Stereo Images, which consist of both a left and right image captured onboard the Pragyan Rover, it said. In this 3-channel image, the left image is positioned in the red channel, while the right image is placed in the blue and green channels (creating cyan).
The difference in perspective between these two images results in the stereo effect, which gives the visual impression of three dimensions. Red & Cyan glasses are recommended for viewing in 3D. NavCam was developed by LEOS/ISRO. Data Processing is carried out by SAC/ISRO. At present both the lander and rover are in sleep mode. Awaiting their awakening around September 22, 2023. UNI


The Nokia 808 Pure View is probably the biggest announcement so far at Mobile World Congress 2012 in Barcelona. The stand out feature (literally) on this device is the camera. The huge 41 Mega-pixel Camera phone from Nokia was a surprising development. Yeah sure, we expected a super camera-phone to be announced today, but I doubt anyone expected it to be a 41MP Whopper!
Apart from the ability to shoot images at that massive resolution (which is explained in the press release below), the phone also shoots videos at 1080p at 30FPS (a first for a Symbian Device). It also records audio at CD-Like Quality. There were a bunch of stop motion movies shot using the N8. This though, would definitely top those!

Published February 27, 2012 | By Nokia – Press Release
Nokia 808 PureView ushers in a revolution in smartphone imagingNokia sets a new industry standard with the first in a range of high end experiences based on exclusive Nokia PureView imaging technologies.
Barcelona, Spain – Nokia today ushered in a new era in high-end smartphone imaging with the Nokia 808 PureView. This is the first smartphone to feature Nokia PureView imaging technologies, bringing together high resolution sensors, exclusive Carl Zeiss optics and Nokia developed algorithms, which will support new high-end imaging experiences for future Nokia products.
The Nokia 808 PureView features a large, high-resolution 41 megapixel sensor with high-performance Carl Zeiss optics and new pixel oversampling technology. At standard resolutions (2/3, 5 and 8 megapixels) this means the ability to zoom without loss of clarity and capture seven pixels of information, condensing into one pixel for the sharpest images imaginable. At high-resolution (38 megapixelmaximum) it means the ability to capture an image, then zoom, reframe, crop and resize afterwards to expose previously unseen levels of details. With superior low-light performance and the ability to save in compact file sizes for sharing in email, MMS, and on social networks, the Nokia 808 PureView makes it possible for anyone tocapture professional looking images in any conditions.
In addition to superior still imaging technology, the Nokia 808 PureView, also includes full HD 1080p video recording and playback with 4X lossless zoom and the world’s first use of Nokia Rich Recording. Rich Recording enables audio recording at CD-like levels of quality, previously only possible with external microphones. The Nokia 808 PureView also features exclusive Dolby Headphone technology, transforming stereo content into a personal surround sound experience over any headphones and Dolby Digital Plus for 5.1 channel surround sound playback.
“Nokia PureView imaging technology sets a new industry standard by whatever measure you use,” said Jo Harlow, executive vice president of Nokia Smart Devices. “People will inevitably focus on the 41 megapixel sensor, but the real quantum leap is how the pixels are used to deliver breath-taking image quality at any resolution and the freedom it provides to choose the story you want to tell.”


LIDAR (Light Detection and Ranging) is a remote sensing technology used to create three-dimensional mapping of the Earth’s surface. LIDAR emits high-frequency light most commonly from an overhead laser on an aircraft or helicopter and measures its reflectance with a scanner to produce an accurate, geo-referenced location of each point or object on the earth’s surface as well as its height. The result is a dense, three-dimensional point cloud of an area that can be used with photogrammetry to produce highly accurate three-dimensional digital elevation and digital terrain models (DEM and DTM).
AJD Geospatial Concepts has experience in using LiDAR point cloud data to prepare 3D DEMs and DTMs and manipulating them to analyze flood inundation, building heights and line of sight, parkland topography and trail location as well as in corridor mapping, building and feature extrusion. We are also skilled in using LiDAR for vegetation analysis and changes in forestation and site selection.

So, you’ve been questioning Laser for Taurus Revolver? If you’re brand-new to weapons, adding lasers to your tool may seem … extreme.
Yet, lasers have actually truly happened a favored weapon tool.
Laser sights are little devices attached to, or might be a fundamental part of, your tool that task a laser light beam on to your target. This is made use of as an included recommendation factor in the sight picture: back sight, front sight, laser dot, as well as likewise target. The eye ordering result of the laser in conjunction with the sight photo permits much faster sight positioning as well as additionally target purchase. This is vital in a self-defense scenario.
There are a couple of various positioning selections for hand weapons: grip, back sights, trigger guard, internal introduction pole, and rail.
A laser hold affixes to the grip of your tool. Many have a turn on the back or side of the hold that activates the laser immediately from the stress of your hand. Different various other lasers ought to be deliberately turned on. Make certain the laser you choose is produced especially for the make in addition to model of your hand gun. While the laser hold is very practical to make use of, it has to be used with a right hold to cause. And also as there are extremely couple of left handed versions, if you are left handed it may obstruct the laser.
Rear Sight Lasers
Back Sight lasers are simply that. They connect to your back sights as well as likewise are light-weight along with really easy to attack. Numerous shooters favor these lasers taking into consideration that they do not add much mass to the tool. Nonetheless, some say that considering that they are smaller as well as also lighter, they can be less reliable.
Trigger Guard Set Up Lasers
Trigger guard put laser sights are terrific if you desire to make use of these sights on many weapons. They are extremely functional as well as can be utilized on different weapons. They are larger than various other lasers nonetheless that likewise makes them a lot much more effective. However, trigger guard lasers typically call for a new holster. A second issue that might be experienced is that the mounting support might not give a secured add-on to the tool, therefore accuracy can also be influenced.
Review Rod Lasers
If you want to maintain your holster and not transform the form as well as additionally weight of your gun so substantially, take into account a laser that changes the inner guide pole. While this style is actually luring, installment is a great deal extra complicated than other lasers and also you dropped the capability to change these sight for windage or elevation.
Rail Mounted Lasers
One of among one of the most common lasers are rail installed Laser for Taurus Revolver. They might not be the tiniest however they are very easy to affix. You just ought to make sure you have sufficient rail area. Much like with the trigger guard placed lasers, these can have worry about the positioning bracket holding the laser flawlessly still.
After you pick the laser sight mount, you’ll have to pick whether you prefer a red or green laser.
Red lasers can be sensible due to their toughness as well as more economical manufacturing expenses. They have a larger temperature degree operational array as well as are ideal in between 15 along with 120 degrees Fahrenheit. However, a major disadvantage versus red lasers is day time presence. Throughout the day, red can commonly only be seen roughly 25– 30 lawns.
Green lasers, on the other hand, have daytime visibility approximately 100 lawns. They are much better to the center of the noticeable light array than red lasers making them additional noticeable throughout day light. This is optimum for target shooters that exercise primarily in daytime hours. However, Environment-friendly lasers require a lot more power, that makes their battery life half that of red lasers. They are additionally somewhat more sensitive to temperature along with are practical in between 40 and additionally 100 level Fahrenheit. Likewise, thinking about that green laser sight development is more advanced, they are far more pricey than red lasers.
At some point when selecting a laser, bear in mind your implied use, environmental problems, along with sort of gun in order to situate the one that functions best for you.


I have been engaging in analyzing sensor network data for over 10 years. One of the key techniques we have been working on has been outlier detection in data streams or time series. For many monitoring applications, identifying abnormal events is an important analytic task. Some of our studies in outlier detection from large datasets were published over 20 years ago but are still well-cited today.
Recent applications include ocean monitoring and detection of gravitational waves by laser interferometers. Both applications are not only temporal but also geospatial in nature.
I am not currently supervising any students.

A script and supplementary materials for a lesson on light propagation and optical fibers.
Thanks to the invention of an optical fiber, it is possible to significantly increase the speed and bandwidth of the data transmission. Replacement of classic transmission cables, where the signal is transmitted by electrical impulses, by optic fibers made the high-speed Internet available also for individual users.
Proper selection of the materials for optical fibers production and the choice of the appropriate wavelengths used for transmission allow a creation of multi-kilometer sections of telecommunication networks without any electronic devices for the to the signal amplification.
Fiber optics are also excellent as sensors such as temperature and stress sensors. Because they are built entirely of dielectric materials, they are completely immune to any electromagnetic interference.
Fiber optics as sensor elements are used in the most demanding applications such as aerospace, mining and, for example, wind turbine blades monitoring.
High-speed data transmission industry is one of the fastest-growing areas of business. Many leading manufacturers of fiber optic networking equipment invest enormous resources in the development of new technologies and are constantly looking for professionals in the field.
Fiber optics has great potential for interdisciplinary applications:.
- Telecommunications - as the primary component of the telecommunications network
- Sensor technology - the use of optical fibers as super-accurate measuring elements resistant to electromagnetic interference
- Medicine - use in endoscopy, surgery, ophthalmology, in examining biological fluids
- Chemistry - as sensors e.g., concentration of various solutions

First in a 3d movie you have double imaegs of everything and one can only go to the right eye and one only to the left. The glasses have to block the image for the other eye. To do this there are 3 main 3d formats.1. Anaglyph It uses two colors and several color combination can be used. If red and blue is used then all imaegs for say the left eye are red and all right eye imaegs are blue. Then the red and blue lenses block the opposing color so that that eye only gets one image. So any device that can produce color can do this format.Now for the other two formats just a regular tv can't do them because of the way they work.2. polarized This uses polarized light waves. All right eye imaegs have a clockwise polarized light wave, and all left eye imaegs a counter clockwise polarized light wave. Then the lenses of the glasses block the opposing light wave. A regular tv can not put out two different light waves. There are polarized 3d tv's but the screen must have a kind of coating on it so all even numbered horizontal lines put out one light wave and all odd numbered horizontal lines put out the other light wave.3. field or frame sequential This format uses shutter glasses. On the glasses when one lens opens the other lens closes and they do this back and forth very fast. When a lens is open then the image for that eye flashes on screen. Tv's and dvd players were never made to flash back and forth between double imaegs and sync them up with some glasses, so you need a tv that can to this some how. This is the format that tv makers are going for at the moment, not polarized like most theaters are using. I have been to an Imax theater that uses the shutter glasses.

Light Emitting Diodes or commonly known LED lighting is a new approach to creating lighting devices that offer a greener alternative to Compact Fluorescent Lighting (CFL), Halogens and notoriously inefficient incandescent lights
Greener Ideas manufacture and supply a complete range of “plug & play” LED lighting products specifically for the Australian market capable of meeting all lighting needs.
Our diversified product range continues to grow by following LED Lighting advances, combined with innovative product designs and improved lighting efficiencies helping save energy and the environment.
Unique products & services allow us to create distinctive products with substantial energy savings.
Led lights have many advantages over conventional lights. They are the cutting edge to the light industries answer for efficient & safe lighting. They give a very clean light with no UV, have a very long lifetime that is over 50,000hrs, and use very little power making them unquestionably the most efficient lighting products available.
By definition LED lighting is the cheapest to run and the most environmentally friendly.
Advances in LED technology have enabled Led Tubes, Bulbs and Down Lights to be produced which simply replace the existing ones, providing the same amount of light but with a 65 – 95% reduction in electricity consumption. Whilst this in itself is enough reason to make the switch, further health and safety benefits associated with the products ensures a cleaner, quieter and safer working environment There are three main reasons why LED lighting is superior to the two main lighting options we currently know of – CFL’s and incandescent.
LED lighting is known to use about 10% of the energy used by traditional incandescent lighting. Incidentally, incandescent light bulbs only use 10% of the energy they consume for lighting, the remaining 90% of energy is wasted as heat loss. CFL lighting is somewhere in between this two extremes, using about 65 – 85% more energy than LED lights use.
2. Useful life
The average lifespan of LED lighting is expected to be about 8-15 times of an incandescent light, based on different manufacturers. LED lights can work over 50,000 hours. Where as CFL’s work from 6,000 to 15,000 hours and incandescent about 5,000 hours. LED’s offering significant maintenance and replacement cost advantages.
3. No Hazardous Materials
The main difference between LED and CFL lighting is the use of mercury (Hg) vapors in the CFL tubes/bulbs. Thus, making the disposal of CFL’s a key issue for homes, businesses, local towns and municipalities. Harmful chemicals end up in land fill which eventually filters through to our water tables and water ways.


Digital post processing can be accomplished by using GIMP or PhotoShop. This can include:
- Contrast enhancement: Dark parts of the image are made darker and bright parts are made brigher. THis often increases the crispiness of the image without the need of sharpening.
- Sharpening: The software detects corners and locally increases image contrast.
- Stitching: Several overlapping images are combined into a single larger picture using panorama software. This is frequently done when the magnification is too high for the camera to capture the whole specimen at once.
- Stacking: Several images taken at a different focus level are combined into one final, completely sharp image.
- HDR imaging: Several images with different brightnesses are combined to produce a final image in which all parts of the picture are correctly exposed.
- Cropping: This is the removal of unnecessary parts of a picture.
- Averaging: Several images of the same specimen are averaged. This improves the signal-to-noise ratio of the image and also removes movement. Only the constant parts of the picture will be shown.
- Background cleanup: this is the manual removal of dust from the background. The picture will simply look much better this way.


Want high-purity single photons, but with control over their temporal shape? A result from our collaboration with Marco Barbieri’s group at University Rome Tre, Heralded generation of high-purity ultrashort single photons in programmable temporal shapes, explains how, and is now published in Optics Express.
One of the bigger limitations of downconverted photon pairs is their tendency to be spectrally entangled, which can be harnessed for quantum advantages in some cases but ruins the interference of photons from distinct sources. By designing specialized sources pumped with broadband laser pulses, it is possible to engineer situations where the time-frequency correlations demanded by the energy conservation of the pump are offset by the conservation of photon momentum in the downconversion material. In these cases though, you are stuck with the photon shape corresponding to the demands on the downconversion medium, limiting their usefulness and adaptability.
In this work, we make use of a phasematching condition known as asymmetric group-velocity matching, where the pump pulse and signal photon travel together, but the idler photon walks off in the medium. This produces a situation where the signal maintains roughly the same temporal width as the pump, but the idler becomes much much longer. In the limit where the walkoff is longer than the pulse widths, the photon pair becomes approximately spectrally separable. Going one step further, the idler photon’s temporal shape is defined entirely by the amount it walks off from the pump, whereas the signal’s shape is defined by the spectral shape of the pump. In this way, custom-shaped photons can be generated by simply shaping the pump pulse, as seen for the Hermite-Gaussian shapes in the figure above.
Of course, there are problems. Due to the sinc shape of the phasematching, the idler is much purer than the signal, as we measure through second-order correlation functions. However, this balances out when the signal photons are heralded by an idler detection in the main peak.

Can You Trust Autofocus with Your Digital Camera?
Text and photography copyright © Darwin Wiggett. All rights reserved.
I was testing the sharpness of a couple of Canon lenses the other day when I discovered something that blew me away. I got much sharper photos by manually focusing my lenses than if I used autofocus! Right away I thought something must be wrong - the camera must be at fault (maybe that rear focus problem that has haunted some Canon cameras) or maybe the lens was faulty or something like that. How could manual focus give me significantly sharper results than autofocus? Well after testing all my lenses on two camera bodies (a Canon 1ds Mark II and a Canon 1ds Mark III) and then testing my girlfriend's Nikon D200 with several of her lenses, the conclusion remained the same: Careful manual focus always gave me better results than autofocus did!
I first noticed the difference when using my Mark III while testing my 24-70mm f2.8L lens. I used autofocus at f2.8 to make an image of rock details on the beach and then repeated the same picture, but this time I used manual focus and the 10X magnification feature in "live view". With live view, you can see precisely what the sensor sees on the LCD and magnify the view 10 times for critical focus. The differences were huge!
I tried autofocus at various apertures but the results were always the same - live view, manual focus gave the sharpest results in spite of gains in depth-of-field with smaller apertures. When I tried the same test with my 135mm f2.0L lens on the Mark III and live view, manual focus won again.
I tried every lens I owned, but got the same results. It wasn't a problem with the lenses.
To be sure the problem was not with my Mark III (Canon has had autofocus issues with the Mark III series), I used the same lenses on my Mark II and got the same results with autofocus as I did with the Mark III.
In fact, every lens I used on either camera gave me the same results. There were no differences in focus quality when using autofocus on either camera.
Live view is a tremendous asset for critical focus, so maybe comparing autofocus performance with the minute and critical manual focus advantage offered using live view was not really fair. I decided to use my girlfriend's Nikon D200 to see if plain old manual focus using the viewfinder was as good as using autofocus (the D200 does not offer live view). Plus, I wanted to make sure that poor autofocus performance was not just a Canon problem! Using the Nikon D200, I was completely surprised by the results. I could always focus the image sharper just using the viewfinder and manual focus than the camera could by using autofocus.
Autofocus with the Nikon was just as "imprecise" as it was using the Canon. Autofocus is pretty good with all of the cameras and lenses I tested but not as good as the human eye. In the field I now often let autofocus do its "best" and then I check the results using live view. I almost always need to re-adjust the focus slightly to get the optimal results. Simply put, I no longer trust autofocus when I am shooting landscapes.
What's the moral of this story? Test your camera and lenses to see if your eyes are better than the camera's autofocus capabilities. In all of my tests, I used flat surfaces with good contrasty subjects and leveled the camera for perfect flatness. I also used wide apertures (e.g. f2.8 or f4) so depth-of-field did not mask errors in focusing. I used a cable release and mirror lock-up on a sturdy tripod to insure there was no camera movement. In the real world, using autofocus and a smaller aperture (f8 and beyond) will often "correct" for slight focus errors. But if you have decent eyes and want the absolute best performance from your lenses, use manual focus - especially if your camera has live view.
For years I have owned autofocus lenses but always used them manually for landscape photography so I could pick my focus point for optimal depth-of-field and also not waste battery power. Over the last several years, I have used Canon's tilt and shift lenses for my landscape work. These lenses can only be focused manually. Now that I have discovered just how much sharper manual focus can be, I am glad I have had autofocus turned off for so many years! Check for yourself to see if manual focus works better for you in nature photography.

The Trend of Led Transparent Screen Series
Aug. 14, 2020
The weight of the traditional LED display is generally more than 30kg/㎡, and the structural load-bearing requirement is high. When the LED display is made of special-shaped products, it will be restricted. When splicing irregular shape, there are seams. The traditional LED display requires a large-scale steel frame when building. The structure is time-consuming and labor-intensive and has a certain impact on the shape and aesthetics of the building. LED display screens are opaque. After the project is installed, it will not light up during the day. The black area will affect the appearance of the building, block sunlight and sight. Coupled with vicious competition among LED display manufacturers, profits are extremely low. Companies could only survive through independent innovation, find new ways, and differentiated competition in products. The high-transparent LED transparent screen series can effectively solve a series of problems above the normal LED display. Our led transparent screen, adhesive transparent screen, led transparent film screen is light, thin and beautiful, it does not affect the appearance of the building without lighting; high permeability guarantees the lighting requirements and viewing angle range of lighting structures between floors, glass facades, windows, etc., and easy to install and maintain, completely change the limitations of normal LED display on glass.
1, Advantages and Opportunities of Glass Led Display
LED transparent screen has become one of the most watched display products in the past two years with its transparent and beautiful characteristics. The 50%-90% transparency rate of LED transparent screen greatly reduces the impact of LED display on the appearance of buildings. In addition, it is installed close to the glass curtain wall, which has avoided the approval of outdoor advertising. Even in the United States, where advertising monitoring is very strict, it has been accepted and welcomed by the government and businesses. Because it is mostly installed behind the glass curtain wall, even when it is not working during the day, it will not cause any impact on the surrounding environment. And when playing the advertisement, when designing the advertisement content screen, the unnecessary background color is removed and replaced with black, only the content is displayed, and the appropriate part is not illuminated during playback, which is a transparent effect. It can greatly reduce light pollution and reduce energy consumption. It can achieve more than 30% energy saving than ordinary LED displays.
With its brand-new visual experience and application experience, LED glass wall screens occupy a place in the market with unique display methods, thin and light appearance design, and high-end fashionable technological atmosphere. With the development of the times, the current urban curtain wall construction , New advertising presentation, landscape exhibition, shopping mall canopy and other fields have unique advantages, glowing with a brand-new display image, and gradually attracting people’s attention, the market has unlimited business opportunities. This product is a new growth point of our company's operating income and profits, quickly occupying the market, and improving the brand's influence and popularity of the company.
2. Current Status, Level and Development Trend at Home and Abroad
Compared with the Chinese market, the overseas LED display industry accounts for a relatively small proportion of global sales. In general, the world's current LED display industry is concentrated in the Pearl River Delta region of China, occupying almost 80% of the entire LED display market sales. At present, the world has initially formed an LED display industry pattern centered on the three major regions of Asia, North America, and Europe. As an earlier and faster mature product in the LED industry, LED displays are currently widely used in outdoor advertising and sports all over the world. Venues, transportation and performances, as well as various occasions such as exhibitions, leases, and gatherings.
Under the influence of the external macroeconomic downturn and the internal price wars of the industry, overcapacity, disorderly competition and other factors, the waterproof and high-permeability rental LED transparent screen developed by our company has broken through the technical breakthrough of extremely transparent, minimalist, advanced concept, Novel and unique features, based on unique structural design, differentiated competition with conventional LED screens on the market, focusing, exerting efforts and intensive cultivation of the market segment of LED displays.
3. Market Prospects
Products in the emerging segment are the hot spots for the development of the LED display industry. The market value of LED transparent screens in 2025 will reach 87.2 billion US dollars. The market demand for transparent screens in my country is very huge, and the market development efforts are far from enough. Just take the glass curtain wall market as an example. According to relevant information, the total area of modern glass curtain walls in China has exceeded 70 million square meters, and its market potential is very huge. The advertising value of this market has not been fully developed. With advertising resources increasingly depleted, glass curtain walls are a new blue ocean field. The scope of this field is very wide, such as city landmark buildings, municipal buildings, airports, automobile 4S shops, hotels, banks, chain stores and other glass curtain wall buildings with advertising commercial value.

Real-time Optical-flow Computation for Motion Estimation under Varying Illumination Conditions
The optical flow approach has emerged as a major technique for estimating object motion in image sequences. However, the obtained results by most optical flow techniques are poor because they are strongly affected by large illumination changes and by motion discontinuities. On the other hand, there have been two thrusts in the development of optical flow algorithms. One has emphasized higher accuracy; the other faster implementation. These two thrusts have been independently pursed, without addressing the accuracy vs. efficiency trade-offs. The optical flow computation requires high computing resources and is highly affected by changes in the illumination conditions in most of the existing techniques. In this paper, a new strategy for image sequence processing is proposed. The data reduction achieved with this strategy allows a faster optical flow computation. In addition, the proposed architecture is a hardware custom implementation in EP1S60F1020 FPGA showing the achieved performance.

The clear sky is waiting to be unveiled.
You may think that night vision is for the military, but in recent years it has been made available to civilians. With this new technology, people are now able to hunt varmints at night using these scopes which have helped them see better than they ever could before!
Upgrade your hunting game with the best generation 3 night vision scope.
Night vision technology is becoming more advanced, and hunters are constantly on the lookout for better equipment. In this article I will talk about some of the best night vision scopes that you can find in stores today to help make your hunting experience a successful one.
Before you start shopping for night vision equipment, it is important to know the different types of technologies and how they work. Technically speaking there are a few different categories of “night vision” technology with various features that may or may not be worth your time depending on what you’re looking for in an optic device.
Movies often show actors purportedly using “night vision” to see at dark, but this isn’t entirely accurate; before purchasing any type of nightvision optics, one should consider its advantages and disadvantages as well as their intended use so they don’t waste money without considering other options first!
The military has been at the forefront of night vision technology since World War II, and while recent advancements have still not made it available to regular civilians. Night vision equipment does this in several ways including by amplifying light from stars or moonlight as well as enhancing digital signals.
The technology depended on gathering infrared light and converting it into visible light, but the equipment was large, heavy, and required an external source of illumination. Generally this type of technology is considered Generation 0 as they are no longer in use or manufactured. Current versions gather available ambient lights (hence their name “starlight scopes”) to amplify these images for viewing without a need for extra lighting sources like flashlights before transmitting them to viewers through green-tinted lenses similar to sunglasses that filter out glare from bright headlights at night while still allowing color vision. From goggles designed specifically with hunters in mind who might be tracking prey after sunset until portable units mounted onto rifles used by military snipers deep behind enemy lines nighttime operations can now function effectively even when all
Get the perfect shot in the dark.
As a civilian, you may think your use of night vision would be limited to hunting or military activities. With the latest technology available called Generation 3 Filmless Image Intensifier (sometimes referred as Generation 4), this is not true anymore! This new advancement in infrared sighting has revolutionized how we can see and interact with our environment at nighttime through an electronic eyesight without any need for light source like moonlight or starlight. Just imagine what it feels like when you are walking on top of leaves during dead-of-night while wearing these goggles–you will feel so empowered that nothing else matters except keeping whoeever’s backside from being illuminated by them all the way down to zero range.”
Digital camera technology developed to function in the dark with better sensitivity than ever before. The development of digital night vision equipment soon followed, and these devices have several advantages over older models-digital sensors are immune from damage by bright light for example.
Digital night vision equipment is the latest and greatest in technology. The sensors used have virtually unlimited lifetimes, making them much more durable than traditional light amplification equipment. These digital scopes produce fantastic images that are easily converted to other types of files for storage purposes. Not surprisingly, these cameras are cheaper to make as well!
The latest entry into the civilian night vision arena is a technology that uses infrared to detect objects during dark or no light scenarios. This equipment detects long-wave radiation and converts these wavelengths into images that are visible to adults in low-light environments. The hotter an object, the more intense color it displays on the image displayed by this device as its temperature increases when reading other heat signatures around it like people or animals.
The latest entry into military field tools for tactical operations has been under development for over 20 years now – thermal imaging scopes have become increasingly popular with law enforcement agencies due to their ability not only identify subjects at long range but also provide accurate readings of body temperatures so they can be used effectively in cases where human trafficking may be taking
Thermal imaging scopes provide a lot of benefits, but they also have some disadvantages. Thermal imagers can see in total darkness without the use of illuminators to create an image reflected off objects. This is not possible with night vision equipment that relies on light sources and becomes less effective when there are obstacles like fog or smoke blocking its view. One disadvantage thermal images do face is their sensitivity to infrared radiation from things such as glass which blocks them completely; this means they cannot be used through windows for surveillance purposes at all! Thankfully though, it’s easy enough just point your scope rather than looking around if you’re trying to find something specific because while potent those advantages still exist even then: unlike other types of devices, thermal cameras don’t require any
Get on target, fast!
Night vision systems are a great way to see in the dark, but what do you need? The best night vision scopes. ATN NVM 14-2 is my pick for the number one spot on this list because of its sleek design and durability that will keep it running all year round no matter how often use it or where you take your next adventure.
ATN has been producing cutting-edge Gen 3 night vision equipment for over 20 years. The ATN-14D is a multiuse system that can be worn on your head, mounted onto a helmet or firearm, or used as an additional eye in the dark with its hand held design – making it perfect not only for those who are sportsmen but also law enforcement alike. Considering all of these features and versatility at such reasonable prices, this versatile gear may just turn into one of your favorites if you give it chance!
ATN specializes in high quality Generation 3 Night Vision Equipment which they have been developing since 1991. One product from their line includes the NVM 14 D model; unlike most other products designed by AT

Component identification of textile materials is an important issue for studies of cultural heritage collections and science conservation. Portable spectroradiometer technology as a potential technique can be utilized to discriminate mass natural fibers rapidly and nondestructively. The goal of this study was to examine the feasibility of portable spectroradiometer to natural fiber type discrimination in the spectral range covering visible and near infrared (VNIR) (350–1000 nm), shortwave infrared 1 (SWIR1) (1000–1850 nm) and SWIR2 (1850–2500 nm). For this purpose, reflection spectra of four types of natural fibers commonly used in archaeological textiles were measured using a portable spectroradiometer under standardized conditions. The spectral features of four categories of natural fibers in different wavelength ranges were extracted and compared. To further explore the potential of discriminating the fiber types using portable spectroradiometer, principal component analysis in combination with statistical tests was applied. The results indicated that fiber type had a strong influence on the spectral features, which was much more remarkable than the influences of the intra-class variation and physical properties. Moreover, with large inter-class variation and small intra-class variation, SWIR2 was more suitable for fiber type identification than VNIR and SWIR1, which was also validated in the statistical analysis. Besides, the approach of selecting effective principal components in different wavelength ranges could provide a more optimized combination of differential information for the correct assignment of the investigated natural fiber types of textile materials. In general, portable spectroradiometer could be a powerful technique for on-site fiber type discrimination.

The Epitaxy and Physics of Nanostructures (EPN) group at Tyndall National Institute, University College Cork, Ireland is using an X-LSM050A, one of Zaber's X-Series linear stages with a built-in controller, to build a long scan autocorrelator to characterise the pulse-width of a tuneable wavelength Ti:sapphire laser. Zaber's stage is part of a Michelson Interferometer where the pulse-width is measured as a power of a sum-frequency generation (SFG) signal vs. an optical delay. The set-up enables the fast characterisation of pulses with the width of tens of picoseconds. Precisely tailored pulse-width (typically in the range of a few picoseconds) is a critical parameter in resonant quantum dot excitation schemes.

People often use their fingers to sense areas that they cannot see. For example, we may use our hand to search for a pen dropped between the cushions of a couch.
But now this kind of work can be performed easily by Magic Finger.
Magic Finger allows users to enhance the capabilities of such probing. By viewing its real-time video feed on a handheld device, the Magic Finger becomes an extension of the user’s eyes.
For example, a user can look behind them, around a corner or out the window of a car by simply pointing their finger in the associated direction.
What Is Magic Finger:
Magic Finger is a thimble-like device worn on the user’s finger. It combines two optical sensors: a lower resolution, high speed sensor for tracking movement, and a higher-resolution camera for capturing detail.
Magic Finger can identify the object that users touch, tapping different surfaces can trigger different command executions
Easy To Use:
Magic Finger can be affixed to the fingertip using an adjustable Velcro ring. A small plastic casing holds the components.
The case was designed to control the distance between the RGB camera and surface during contact.
Best Part Is:
Magic Finger is able to recognize textures and use the information to understand the environment, or object the user is interacting with, and perform associated contextual actions
