LIGHT UP YOUR LIFE.
You’ve been out on the tail all day and you’ve worked yourself further away from basecamp than you thought. With the sun sliding down towards the horizon faster than anticipated, you realize that you might not make it back before dark.
Driving over rough terrain in the darkness isn’t only challenging, it can be downright dangerous. Is that a dip in the road or a 100-foot drop? Fortunately, you’ve outfitted your rig with the latest in vehicle-mounted lighting to figure that out and get you back to home base safely.
KC HID lights combines a high-voltage ballast to energize two electrodes sitting inside a sealed hub.
When you decide it’s time to shop for off-road lighting, consider what your intended use will be. Is it mostly for slower nighttime exploring on some of your favorite trails or high-speed bombing down sandy washes? Your application will determine the light pattern and type of light you need for your pursuits after dark.
Modern off-road lighting comes in three flavors: halogen, high-intensity discharge (HID), and light-emitting diode (LED). Each has its purpose and these lights vary by shape, dimension, cost and performance.
Halogen lights use a tungsten filament encased in a round, sealed bulb with a polished reflector. Inside a filament resides an inert gas used to keep the bulb from darkening over time, as would happen with a standard sealed bulb. The front lens of the bulb can be formed to provide a specific beam pattern as needed. Halogen lights are typically the least expensive type, and their bulb life ranges from about 50 to 300 hours, depending on power rating.
Rigid Industries RDS-Series light bars were designed to conform to curved windshields.
High-intensity discharge (HID) lights use two closely-spaced electrodes inside a sealed bulb, which contains a noble gas. A ballast module is used to step up the vehicle voltage to create an intense light discharge within the gas mixture between the electrodes. HID lamps are more power-efficient than halogen lights, and run somewhat cooler. With no filament to wear as with a halogen light, HID lights can last for about 3,000 to 5,000 hours of use.
As far as technology goes, halogen and HID advancements are all but dead. Light-emitting diode (LED) lights have become all the rage in recent history and are now seen most everywhere. In these, electrical current is passed through a semiconductor junction that causes light to emit. This technique of producing light is by far the most efficient of the three types; plus, LED lighting can be produced to emit a variety of colors and hues of white light.
Unlike halogen and HID lights that use a single point of source per light, off-road LED lights typically use multiple (sometimes many dozens of) individual LED sources to compose a single LED light assembly. One advantage to using an LED bar (and quality counts) over halogen or HID lighting is the smoothness of light distribution over the beam pattern. With multiple sources working to produce the beam, you get a far more consistent blanket of illumination from an LED bar.
KC Gravity Pro6 lights directs 100 percent of the light into the reflector resulting in no light loss.
LED technology continues to advance from not only aftermarket light suppliers but from the vehicle manufacturers, as they continue to develop LED headlight solutions and push them into mainstream offerings, and not just high-end vehicles. LED substrates continue to improve in efficiency, and thus, power capability. Today’s LEDs can produce more output using less space, as well. It wasn’t long ago that LED lighting simply couldn’t compete with HID units for racing applications. As of late, LEDs have proven they have a place in high-power lighting, and they’re here to stay.
KC Hilites Flex LED line is a modular lighting system that allows you to create an array of LEDs of any size you want. Lights can be linked or stacked to gain the array you need, including the use of spot- and spread-beam light patterns.
With LED lighting, there are generally two types of optical technology that light manufacturers use to create the projected beam of light: lens optics and reflector optics. These are the means by which the various manufacturers obtain their beam patterns and lighting output. Lens optics use a medium to manipulate the beam. These offer a smooth/uniform beam but are typically limited by existing, ready-made optics that may not provide good automotive beam patterns. Reflector optics use reflectors to refract the beam, offering an intense beam and custom patterns, depending on reflector design. However, efficiency may be limited by how much light is redirected by the reflector.

Compared to the iPad’s squarer screen, the tablet’s 10.1-inch LCD touchscreen is a little bit brighter than its predecessor and made for watching movies. The new Fire HD 10 is 36g lighter than the one it replaces and employs the slimmed-down and rounded design language first used on the 8in Fire HD 8 last year, giving it a noticeably more contemporary appearance.
Hardware and performance
The 2 MP main camera of the predecessor would be replaced by a 5 MP lens with f/2.4 aperture. The lack of autofocus makes the image sharpness comparable to the 2-MP front-facing optics, and the photographs are likewise blurry. The dynamism in the images are also not very strong, and details and structures are frequently lost in blur. In extremely dim light, our test person is hardly recognizable. Surprisingly well, the Fire HD 10 Plus captures color. We put the rear-facing main camera through additional testing with the ColorChecker port under regulated lighting circumstances, and we examine the 5 MP lens’s color reproduction in contrast to the real reference colors. The colors are faithfully portrayed. The ColorChecker only detects bigger differences in black and grey tones. The front-facing camera only captures moving images in 720p while the image sensor utilized on the back records videos in a respectable quality with a maximum Full HD resolution.


HD-CVI security cameras are a newer HD camera technology. They come in many different types and styles of dome cameras, bullet cameras, pinhole and spy cameras.
We also have pan tilt zoom HD-CVI cameras. The nice thing about HD-CVI is that it can use both coax cable and cat5 network cable to transmit the signal. This is the same type of cabling used in many older analog camera systems. So, this makes it an easy transition for upgrading older analog security camera systems. This is also a big savings if you don’t have to replace all of the cabling.
The other benefit of using HD-CVI is that you can run the cabling at much greater distances than you can for other HD security camera systems. IP cameras and HD-SDI cameras are limited to about 300ft whereas HD-CVI security cameras can be run up to 1500ft using RG59 coax or cat 5 or 6 cabling.
If you are looking for a great image quality at a great price then HD-CVI security cameras are the way to go. Where analog has difficulty producing a recognizable face or reading a license plate from a distance HD-CVI security cameras produce a much higher resolution image which makes identification much easier.
HD-CVI Security Cameras
HD-CVI Camera Resolutions
There are many different types of CCD and CMOS sensors on the market for security cameras. Some of the manufacturers are Sony, Panasonic and Sharp. HD-CVI broadcasts in HD resolution. Resolutions from 1080p all the way up to 4K are available.
HD-CVI Infrared Security Cameras
The lens is in the center at the front of the security camera and it usually has infrared LED’s around the lens. With bullet cameras the face is flat on the front. The more IR’s the security camera has the better the night vision. There are different strengths of infrared LED’s and the larger and more intense the LED the farther and larger of an area that will be lit up. Basic CCTV bullet cameras will light up to 20m. Some higher end infrared security cameras can light up farther than 90m. Bullet cameras generally have better infrared night vision than dome cameras. This is because more IR’s can be placed around the lens on a bullet camera than can be placed around the lens on a dome camera.
HD-CVI Day/Night Security Cameras
Most HD-CVI security cameras are day/night cameras so they are color by day and black and white at night. Under low light conditions the infrared LED’s illuminate and the camera will switch to black and white night mode.
HD-CVI Security Camera Lens types
The lens on a security camera can come in different focal lengths. Wide angle lenses are the most popular and they come generally in 3.6mm or 4mm. If you want a more closer or zoomed in view the lens can come in 6mm, 8mm 12mm or even longer zoom lengths. You can also get what is called a varifocal lens camera. This is when the lens can be manually adjusted at the camera. A popular varifocal lens is 2.8mm to 12mm. At the time of installation you adjust and focus the camera for the view that you like. There are also motorized zoom cameras that can be controlled from the DVR. The most popular are pan tilt zoom cameras. This way you can not only zoom and focus the lens but you can move the camera position.

In Infrared Photography (IR Photography) a large part of the visible light is blocked out and the invisible infrared light spectrum is recorded.
In the old analog film period a special infrared film was used that was extremely light sensitive and had to be handeled very carefull.
In the new digital photography era no light sensitive film is to be used. The way to get to IR images is to block out the visible light spectrum by very dark red filters. This can be done by either screw-on type IR filters in front of the lens or internal replacement IR filters that go directly before the sensor internally within the camera.
The IR filters come in a variety of strength, meaning the amount of visible light they block and the amount of infrared light they let through creating differnet effects with each IR strenght filter.
As I got inspired to IR photography on a local photography show in August 2012 I bought an older Nikon D1x DSLR camera with front of the lens IR filters. Additionally I bought a Nikon D70 DSLR camera (using a 10.5mm lens with it) and an older point and shoot Cancon 3010 Powershot, both permanently converted to IR with an internal IR filter placed in front of the digital image sensor.
As I am just getting started you will see a learning and playing curve. I totally enjoyed IR Photography right from the start. The images can be very dramatic in a way you can not get them in black and white. A great and dramatic combination is HDR IR photography as the image on top of this page.
For post capture development I use Adobe Lightroom 5, Adobe Elements 9, for HDR conversions I use Photomatix 4.2.4 and for black & white conversions the Nik Silver Effex Pro 2 software.


There are more than a dozen different touch technologies in the tech market, each bringing unique strengths across various industries and applications. Few touch technologies, however, offer the benefits of optical touch: accuracy, clarity, flexibility, reliability, durability, and support for multi-touch gestures. Optical is particularly optimized for the desktop and All-in-One PC market.
How Does Optical Work?
Working in concert, two optical sensors located at the top left and right corners of the screen track the movement of any object close to the surface by detecting the interruption of an infra-red light source. At the heart of the system is a printed circuit controller board that receives signals from the optical sensors. The optical software then compensates for distortions and triangulates the position of the touching object with a high degree of accuracy.
- Clarity of image (no films or coatings on the screen) improves visual experience.
- Fast drag function allows for quick, accurate finger swipes and brush strokes.
- Zero-pressure response makes screens durable and accessible for users of all ages and levels.
- Multi-touch capability enables the screen to support built-in gestures within Windows 7.
- Excellent performance, accuracy, and reliability even in rugged and outdoor environments empower the potential of touch applications.
We offer two great optical touch All-in-One PCs. The All-in-One EA650T, which is built around Intel’s new Thin Mini-iTX standard that allows us to offer our customers the flexibility and customization that we have become synonymous with, and the All-in-One GA650T which in addition to the great features of the EA650T is also Energy Star rated and Epeat certified, making in a truly environmentally friendly machine. You can find out more about CTL’s All-in-One PCs at our website www.ctl.net.

20/20 vision. Perfect vision. The best that the human eye can resolve.
Therefore there’s no benefit in creating a display system that has a higher resolution than that of the 20/20 line of an eye chart. Right?
20/20 vision means that at 20’ (6m) a viewer can identify characters constructed of lines 1.75mm wide and 1.75mm apart. It’s the ability to clearly see this gap and discern the letters of the eye chart that tests a person’s visual acuity. The line thickness of the characters on an eye chart are 1 arc minute (one 60th of a degree) wide when viewed from 20’ away.
Therefore on that premise, a high resolution display in an Immersive theater needs pixels no larger than 1 arc minute wide. That equates to around 10,800 pixels for a dome (180 degrees x 60 pixels per degree), when viewed from the centre of the theater (also assuming the viewer is at the spring-line of the dome), and 4,320 pixels across in a giant flat screen theatre (DIGSS1.1)1 when viewed from the central seat row.
Well, actually that’s wrong. We can ‘see’ objects far smaller than lines that are 1 arc minute wide.
Look around you now. How much of what you see is made up of regular shaped black and white lines equally spaced?
Not much. The World is not an eye chart.
We can see details far smaller than 1 arc minute across. The leaves on a tree, the fur of an animal. The carpet. A hair on the page of a book.
Also consider that we do not need to accurately resolve an object and recognise it to see that it is there, that it exists. In fact we typically enjoy the intrigue of getting closer to an object to discover what it is. Fully and clearly resolving an object is quite different to seeing that it’s there. If 1 arc minute was all that we could see then we would never see the hair on our arms.
Part of the complication is that the resolution of the human eye is not an absolute. How much we can see depends upon the viewing conditions. The amount of light and the contrast of the image play an important part.
Leaving these variables to one side, it is generally agreed that under optimum viewing conditions the human eye can resolve detail as small as 0.59 arc minutes per line pair2 (pair of pixels) which equates to a pixel size of 0.3 arc minutes. This therefore is the generally accepted figure for ‘eye limiting resolution’, more than three times the resolution of 20/20 vision.
Resolution is an important metric for the flight simulation industry for pilot training applications. A level-D simulator (suitable for commercial aircraft) stipulates a display resolution of only 1.5 arc minute sized pixels (3 arc minutes per line pair). Significantly this is because pilots need to be able to resolve the runway lines which are 4 feet apart at 6,876 feet away as they come into land. Fast jet simulators on the other hand are targeting a much more demanding specification of 0.5 arc minutes per pixel. These fast jet simulators are designed as close as possible to eye limiting resolution so that the pilots can identify fast moving objects in the sky.
If we are ever to experience eye limiting resolution in immersive theaters we would need to capture and display 0.3 arc minutes of resolution. This equates to 36,000 pixels across the centreline of a dome and 14,400 pixels across a 70’ giant flat screen when viewed from the central row of seats.
Furthermore, consider that in a dome every audience member bar one is closer to some part of the screen than the person in the center, and that the front half of a giant flat screen audience are significantly closer to the screen than the center row. These audience members would need even more pixels on the screen to enjoy eye limiting resolution (in fact up to 22,600 pixels wide from the front row of a 70’ wide flat screen).
As of 2014 the current state of the art for domes offers around 6,600 pixel resolution (optimistically referred to as ‘8k’) and for flat screens 4,096 pixels. These specifications are driven by the ‘4k’ projection systems now in the market (domes use an array of five or six 4k projectors to cover the dome surface). Once ‘8k’ projectors come on-line at comparable prices and at the brightness levels required (probably 3 to 5 years away) the capability of flat screens will quickly jump to 8,000 pixels and domes to around 12,000 pixels (assuming that the capture resolution and production workflow can keep up).
This may appear unrealistic and out of reach for now, but for those of us who can remember marvelling at 1280 x 1024 resolution at the turn of the century will know that we soon recalibrate to expect higher resolution once we’ve experienced it.
Thus far this only considers spatial resolution (how many pixels). Of increasing importance is temporal resolution (how often), otherwise known as frame rate. Frame rates or fps (frames per second) have been quite stable for many years. 24fps and 30fps have been with us for many years. HFR (high frame rate) 48fps and 60fps are with us now and could quickly be overtaken by frame rates as high as 120fps or even more. High frame rates smooth out the strobing or judder that one can experience, particularly on large field of view screens. With 3D systems HFR can significantly help with edge definition, the means by which we determine the depth of an image using current 3D technologies. HFR can help us see the resolution that is there in the image that is otherwise blurred-out during panning and fast action shots.
The combination of higher frame rates and resolutions approaching eye limiting resolution will help deliver increasingly realistic immersive experiences.

Having the right pair of binoculars makes all the difference when viewing birds. In this birdwatching binoculars review, we’ll compare and evaluate seven top-rated birdwatching binoculars.
- Meopta MeoPro HD 10X42
- Vortex Viper HD 10×50
- Leupold BX-4 10×50
- Leupold BX-5 Santiam HD 10x42mm
- GPO Passion ED 10x42mm
- Zeiss Conquest HD 10×42
- Swarovski EL 10×42
By examining their features, pros, and cons, we’ll help you make an informed decision that enhances your birdwatching adventures.
My goal is more than providing another ho hum top 10 binoculars for bird watching list. I will take you through the exact research process I followed when I purchased my most recent pair of binoculars for birding. I found the perfect pair of binoculars for me and my budget in 2023.
Birdwatching Binoculars Review
I have chosen 40 mm and 50 mm lens sizes for the binoculars I will review below because they are common size preferred by many birdwatchers. My selections for the birdwatching binoculars review includes some of the best 10×42 binoculars for bird watching for casual birders and those with a moderate budget. If most of your viewing is designated to bright sunshine and in the open, unshaded areas something smaller might work like a 30mm size. A smaller size means less ability to render birds in shade, overcast conditions, or as darkness approaches. The bigger lenses let in more light and increase the ability to render birds in less than sunny conditions.
What is the best magnification for bird watching binoculars?
I have chosen one of the most popular magnification sizes in the world of birdwatching binoculars used for birdwatching. The “10” represents a 10x magnification. Likewise, an 8x or 7x or 12x represents the magnification rating for a particular binocular pair.
If your typical bird viewing distance is within 25 – 30 meters from a walking path or sidewalk, the 7x or 8x binoculars are likely fine for that application. But if viewing distances increase beyond that, then a 10x binocular is a more common choice.
Most of my birdwatching has been with a digital camera and a 300 mm budget zoom lense for the past several years. My lens is no longer serviceable, so I decided to go the traditional route and buy some binoculars.
I spent several months searching, researching and wafflling back and forth on the best options for binoculars. I concluded that one pair isn’t enough for all situations, after wasting many, many hours online it became clear to me that there are not a “best” binocular for light / dark conditions, near / far distances, or for short / long hiking distances. So, I did what many people do and picked a good quality binocular option that offers a lot of value for the money.
Birdwatching is a great alternative to pet ownership.
Which binoculars are best for birdwatching?

Bird Watching Binoculars
Choosing the right binoculars for birdwatching can greatly enhance your experience by bringing birds closer and allowing for detailed observations. Whether you opt for the Meopta MeoPro HD 10X42, Vortex Viper HD 10×50, Leupold BX-4 10×50, Leupold BX-5 Santiam HD 10x42mm, or GPO Passion ED 10x42mm binoculars, each model has its own strengths and features that cater to different birdwatching preferences.
Are 7×35 binoculars good for bird watching?
A pair of 7×35 binoculars could be a good choice. Many of those binoculars are lower in cost, lower in amenities and features, but may still offer the occassional user a nice viewing experience. I have an older pair of Vivitar binoculars in that size and they are good all around binoculars. They are typically used as an astronomy-type binocular, or as a multi-purpose option.
What is the best magnification for bird watching binoculars?
Birdwatching binoculars are typically 7x, 8x, or 10x. The 10×40 is a very popular size for birding.
By considering factors such as budget, magnification, objective lens size, weight, field of view, and optical quality, you can select the binoculars that align with your specific needs. Embrace the beauty of nature and enjoy the captivating world of birdwatching with the perfect pair of binoculars by your side.
Sometimes you can save money by buying a pair of binoculars that are used, demo, or open box models. This does come with some risk, but you can often save up to a few hundred dollars. On a high-end pair, it adds up to some serious saving potential.
When selecting birdwatching binoculars, it’s crucial to prioritize the factors that matter most to you. Consider your budget, desired magnification, objective lens size, weight, field of view, and optical quality. Consider how and where you plan to use the binoculars, as well as your personal preferences.
I hope you’ve enjoyed my birdwatching binoculars review.
Remember that the best binoculars for birdwatching are the ones that allow you to immerse yourself in the beauty of nature, observe birds with clarity and detail, and enhance your overall birdwatching experience. Happy birdwatching!

Crop factor, also known as focal length multiplier or lens factor, is a numerical value that represents the ratio of the diagonal measurement of a camera's image sensor to the diagonal measurement of a 35mm film frame. It is typically expressed as a decimal or a fraction.
Calculation[edit | edit source]
To calculate the crop factor of a camera, you need to know the size of its image sensor and compare it to the size of a 35mm film frame. The crop factor is determined by dividing the diagonal measurement of the image sensor by the diagonal measurement of a 35mm film frame.
For example, if a camera has an image sensor with a diagonal measurement of 15mm and a 35mm film frame has a diagonal measurement of 43mm, the crop factor would be 43/15, which is approximately 2.87.
Effects of Crop Factor[edit | edit source]
The crop factor of a camera affects the effective focal length and field of view of a lens. When a lens is mounted on a camera with a crop factor greater than 1, the lens's focal length is effectively multiplied by the crop factor.
For instance, if a lens with a focal length of 50mm is mounted on a camera with a crop factor of 1.5, the effective focal length would be 50mm x 1.5 = 75mm. This means that the lens would have a narrower field of view compared to when it is used on a full-frame camera.
Applications[edit | edit source]
Understanding crop factor is crucial when selecting lenses for a camera. It helps photographers determine the equivalent focal length of a lens on different camera systems. For example, a 50mm lens on a camera with a crop factor of 1.5 would have a similar field of view as a 75mm lens on a full-frame camera.
Crop factor also affects depth of field. Since a lens with a longer effective focal length has a narrower field of view, it tends to produce a shallower depth of field compared to a lens with a shorter focal length.
Conclusion[edit | edit source]
Crop factor is an important concept in photography that affects the effective focal length and field of view of a lens. By understanding crop factor, photographers can make informed decisions when selecting lenses for their cameras. It is essential to consider the crop factor when comparing lenses and understanding their impact on image composition and depth of field. Template:Photography

Many of the Vostok-Europe models feature Tritium tubes (trigalights). These highly specialised light sources are manufactured by Mb-microtec of Switzerland and provide excellent illumination with no external power source and never need to be recharged by the sun or otherwise.
Trigalights are tiny glass tubes that are laser sealed, internally coated with phosphorescence and filled with a minute amount of tritium gas. The permanent light occurs when the electrons emitted from the gas excite the phosphor. They do not require any external power source or require recharging and will glow continuously with a life span of more than 10 years. Click for more information.


Precision black glass balls are used in aircraft slip and turn indicators and other aircraft instrumentation. Black glass balls are also used in flowmeters for many industries including chemical processing and medical. Rotameters are a particular kind of flowmeter, based on the variable area principle. Precision balls provide a simple, precise and economical means of indicating flow rates in fluid systems. In rotameters, black glass balls are used as floats or sight indicators. Standard black glass balls have a density of 0.0914 lb/in3. Many other common rotameter floats are also available from ITI including orange glass balls, stainless steel balls, tantalum balls, tungsten carbide balls, ruby sapphire balls etc.
When polished, both soda lime glass balls and borosilicate glass balls provide an extremely good seal making glass balls ideal for check valves in food processing, pharmaceutical, and photographic processing equipment. Glass balls are used in fiber optics applications because they can be made optically clear.


An eye tracker is a small camera aimed at one or both eyes. This camera uses infrared light. The camera image can be used to measure where you are looking at and to measure your pupil size. Studies that make use of an Eye tracker do research on emotions for example, but most of the time the goal is to look at what you are looking at on a screen. These cameras are only focused on your eyes and therefore do not capture images of your face.
In most Eye Tracking studies, you as a participant will perform a certain task on a computer with the Eye Tracking camera facing your eyes while performing this task. Sometimes you will be asked to place your chin in a so-called chin rest so that your head and therefore your eyes remain in the same place. As a participant, you will perform the examination in a quiet room while the test leader is in the connecting room. You will receive instructions about the task in advance. The eye tracker study can also be combined with other types of measurements, such as physiological measurements, EEG and even MRI. In that case, this will always be clearly communicated to you prior to the appointment.
During the examination you will be sitting in front of a computer with the camera facing your eye, the exact duration depends on the specific study. During the examination you will perform a "task" on the computer. This can look like a (simple) computer game or watching pictures or videos on the screen. How this task looks is entirely dependent on the question and purpose of the research. You will be informed in advance.
You do not need to prepare anything for an Eye Tracking study. However, you may be asked to remove your eye make-up in advance and (if you have both) wear lenses instead of glasses.
In principle, anyone can participate in eye tracking research. However, sometimes it is more difficult to get a good signal if you wear glasses or hard contact lenses, for example. A researcher therefore might choose not to use eyeglass wearers in the experiment. Always take a good look at which target group is being sought for the research you are registering for, and whether you belong to that target group.

Cataract Surgery – ReSTOR IOL
Many people with cataracts also are affected with presbyopia, age-related farsightedness (hyperopia). Unless something is done to correct this condition, such patients will still need reading glasses following cataract surgery. Fortunately, a new intraocular lens has been created that also addresses presbyopia.
The AcrySof® ReSTOR® IOL utilizes revolutionary lens technology to allow patients to see clearly at all distances. Most patients who are fitted with ReSTOR® lenses report that they no longer use glasses or contacts for any activities. More than 21 million AcrySof® have been implanted since 1994, making it the most widely used IOL brand in the world. Now the ReSTOR® IOL makes it possible for patients to eliminate cataracts and treat presbyopia at the same time.

Eye Surgical procedure has actually become a mainstream approach of vision modification, and this short article will certainly explain the benefits as well as disadvantages of 3 various techniques being provided to the medical customer.
Lasik Eye Surgery
LASIK is the acronym for Laser-Assisted Sitting Keratomileusis and also is an eye medical system which completely deals with vision by eliminating a thin layer of the cornea. This treatment works best on clients with modest to high levels of nearsightedness (nearsightedness), low to modest degrees of hyperopia (farsightedness) and also astigmatism related to myopia, and also who have thick corneas. It is the most well-known medical vision correction technique.
Individuals with regular eye view see things plainly because pictures are brought into a proper centerpiece by the cornea as well as lens of the eye. Preferably, the cornea's curvature is equally matched to its size in a normal eye. People with astigmatism, myopia or hyperopia have off-and-on formed corneas, so the things seen are not concentrated properly. LASIK adjustments corneal form by precise removal of corneal tissue, and also by doing so corrects the eyes' concentrating power.
There are, however, threats to LASIK eye surgical treatment.
There is a remote possibility of complete loss of vision. If this occurs, it is normally due to the fact that the person had a pre-existing problem which ought to have precluded the surgical treatment in the first place, such as pregnancy, cataracts, joint inflammation, diabetic issues, glaucoma, or lupus. Individuals with huge pupils are also poor candidates for LASIK. Dry eye syndrome will certainly be aggravated by this procedure.
A couple of clients whine that they permanently see "ghost" images, have actually obscured vision, reduced comparison as well as bad night vision. When LASIK wased initially introduced, 5% of patients had post-operative grievances; nonetheless, refinements in the procedure have actually created this rate to go down to much less than 1% if LASIK is executed by experienced professionals as well as clients are effectively screened before surgical procedure. If problems do happen, they can typically be resoved by a retreatment.
FDA has approved LASIK laser eye surgery given that 1998. While there are a great deal of satisfied individuals, there are nevertheless no long term research studies about its impacts. Understand the restrictions as well as the threats of LASIK eye surgical treatment before you sigh up for the treatment.
Though much less popular, these little implants could boost vision in patients with mild to moderate myopia without the danger of irreversible eye damage integral in the cells removal strategy of LASIK. Intacs are semi-circular disks implanted in the cornea which extend it to presume a flatter form. Though slightly much less accurate compared to LASIK, they are removeable and also Read Full Report changeable, so if the person has an unforeseen over- or under-correction, the implant could be gotten rid of and also another of a different size inserted to acquire the preferred improvement. The implants lie at the edge of the cornea, so the main visual area is entirely intact and intact, and also the strength of the cornea is undiminished, making it a much better choice for pilots as well as those that take part in contact sports where eye injury is a possibility.
Intacs disagree for extreme myopia as well as greater than small astigmatism (1.00 diopters), as the cornea can just be stretched thus far. If the Intacs are removed, vision returns to its preoperative level. In addition to vision adjustment, Intacs are additionally used to treat keratoconus.
Intacs are FDA authorized and also Ten Years studies have revealed no significant issues with Intacs and very few client grievances; nevertheless, since the procedure takes extra training than LASIK, there are fewer eye surgical treatment facilities providing it. Nonetheless, the Intacs website offers a checklist of experts in each state, also a few in Canada, Europe as well as Mexico.
Since many individuals do not intend to take the chance of LASIK and Intacs can not click this link help those with extreme vision troubles, intraocular lens implants (IOL) are a new alternative authorized by the FDA in 2004 to fix modest to severe nearsightedness. The Artisan lens, produced by Ophtec, resembles the sort of lens implant used to recover vision adhering to cataract eye surgery.
The new IOL, called the Artisan, is planned for only people who have 2.5 diopters or less of astigmatism.
The artificial lens does not change the all-natural lens, but is placed before it. The main issue discovered with the implant was the steady loss of endothelial cells in the corneas of clients that obtained the implants. The endothelium is a layer of cells that line the undersurface of the cornea as well as are essential in keeping the cornea clear. A three-year research study showed a continuous constant loss of endothelial cells of 1.8 percent a year. Now, no one could anticipate whether this loss will certainly continue at the exact same rate forever, or even its effect on corneal feature.
To reduce lasting effects of the tool on the corneal endothelium, the FDA is requiring that the new lenses be identified to specify that they should just be implanted in people whose corneal endothelial cells are thick enough to endure small cell loss.
More major issues were couple of: retinal detachment (0.6%), cataract advancement (0.6%), and corneal swelling (0.4%). The FDA is requiring Ophtec to perform a five-year follow-up survey of its implant patients to better analyze the post-surgical incidence of cataract advancement, retinal detachment as well as various other ocular conditions.
The Craftsmen lens is intended to be a permanent implant.Though it can be gotten rid of operatively, vision might not always go back to just what it was before obtaining the lens. Due to the fact that it does not influence astigmatism, people with this problem may still require glasses.


Trained with raw stereo motion sequences in a self-supervised manner, our model learns to predict object motion (speed and moving direction) together with the scene depth using sequence of stereo images and object proposals as input.
We present a system for learning motion maps of independently moving objects from stereo videos. The only annotations used in our system are 2D object bounding boxes which introduce the notion of objects in our system. Unlike prior learning based approaches which have focused on predicting dense optical flow fields and/or depth maps for images, we propose to predict instance specific 3D scene flow maps and instance masks from which we derive a factored 3D motion map for each object instance. Our network takes the 3D geometry of the problem into account which allows it to correlate the input images and distinguish moving objects from static ones. We present experiments evaluating the accuracy of our 3D flow vectors, as well as depth maps and projected 2D optical flow where our jointly learned system outperforms earlier approaches trained for each task independently.
Qualitative results of our method. From left to right, reference image, depth, optical flow and instance-level moving object mask.

Optical Aperture Synthesis (OAS) offers the possibility to achieve surveillance images with more than 100x the information content or 10x the range of current equipment. Our research in this area included an initial study of the risks associated with implementation of OAS in military applications and examined both passive and active synthesis imaging methods.
On this page you will find a brief mathematical description behind the principle of optical aperture synthesis and suggestions for further reading.
The complex visibility of an interference pattern produced by a pair of apertures (i.e. one particular baseline vector) is one particular Fourier component of the source brightness distribution (from the Van Cittert Zernike theorem). You can use a range of baselines i.e. aperture separations to obtain a range of spatial frequencies. The measured complex visibility is otherwise known as the mutual coherence function, which is given by:
when becomes 0 we have the mutual intensity or complex visibility:
- intensity in the direction where is a unit vector.
- the vector separation (baseline vector).
- is the component of the wave vector in direction
- is the central wavelength.
- is the solid angle.
In aperture synthesis we measure at different values of aperture separation and we get by inversion of equation 1 above.
The following is known as the fundamental equation for aperture synthesis:
then given a number of measurements of at different points in the UV plane i.e. for different point apertures we need to invert the equation to get . Using the inverse FT:
When only measured at a limited number of points in the UV plane we need to replace the integral by the summation:
W is a weight factor associated with the jth point. Then is the “dirty map” it is the convolution of the true I with a point spread function. So:
In practice the complex visibility includes instrumental and environmental perturbation effects which produce phase errors. Individual aperture phase errors may be eliminated by summing the phases round a closed loop of baselines i.e. phase closure. However phase closure should really only be applied to situations where signal to noise ratio is poor, otherwise it is rather an inefficient method of aperture synthesis. We are demonstrating the use of Redundant Spacings Calibration instead. This method is based on the principle that when the target is a large distance away the information collected by identical aperture pairs or baselines should be the same. Any difference arising must therefore be due to localised phase errors such as in atmospheric turbulence or in system calibration and a single aperture involved in a redundant baseline can be "driven" so as to match the phase of the resulting interference fringes. This self-calibration of the system can be done in a very small time scale without the need for "off-line" computations, again making it ideal for use in mobile imaging systems.
The phase relations can be regarded as a set of matrix equations to which there are more unknowns than knowns. Introducing redundant conditions makes the matrix full rank and a unique solution can be achieved.
This method does not give absolute object phase information. A relative phase plane is defined by three apertures and the rest are driven to match. However absolute phase information is not essential to reconstruct the image.
The principle of using multiple collecting apertures to sample an object can be used in reverse in a technique called Fourier telescopy. Whereby an array of apertures are used to project interference fringes of varying spatial frequency onto the target and by applying a phase shift to displace the interference pattern by π radians, a camera can integrate up the reflected light and the data collected is then exactly the form of the object's Fourier transform. This technique allows high resolution images to be taken from low resolution quality optics even with a wide field of view, gives high signal to noise ratio independent of resolution and can be used with RSC. This is useful in many aspects of metrology.
Because source coherence is required to produce a spatially coherent interference pattern on the target, laser speckle becomes an issue.

Satellite Image Compression Using Compressive Sensing
Satellite images are multispectral or hyperspectral images, which are important for earth observation and military
reconnaissance. However, there exists big incompatibility between the transmission capacity of satellite channel and large amount
hyper spectral data. There are spatial and spectrum redundancy in hyper spectral image. As to exploit spectrum correlation
sufficiently, it must be to pre-process hyper spectral image. In this paper, we propose a novel acceptable complexity lossy hyper
spectral image compression scheme. Conventional approaches to sampling signals or images follow Shannon’s celebrated theorem,
which says that the sampling rate must be at least twice the signal bandwidth (the so-called Nyquist rate). In fact, this principle
underlies nearly all signal acquisition protocols used in consumer audio and visual electronics, medical imaging devices, radio
receivers, and so on. Compressive sampling, also known as compressed sensing or CS, a novel sensing sampling paradigm that goes
against the common wisdom in data acquisition. CS theory asserts that one can recover certain signals and images from far fewer
samples or measurements than traditional methods used.

Kodak DC280 Review
The LCD refresh is an improvement on older Kodak’s but still isn’t up to the quality of other digicams and still has little “sparkles” of colour noise in shadows. As with all Imaging Resource camera tests, we encourage you to let kdoak own eyes be the judge of how well the devices performed: Nikon Japan officially lists the D and D as discontinued.
At the high resolution, best quality setting, the average file size is about K. Higher drains can greatly decrease the effective capacity. This number, of course, will vary depending on the Quality setting Best, Better, Goodand the Resolution level setting High, Standard.
Also as with other cameras, the digital zoom only works when the LCD is turned on, because you’d have no way to tell what portion of the image was being viewed otherwise. Operation is quick, although you’re aware that the camera takes quite a while to write out to the CF card the activity LED indicates when kodaj camera is writing to the card.
Then, you can use the DC’s Border feature to add the borders to your image prior to capture. Find out what’s new and notable about the Z6 in our First Impressions Review.
Senior Editor Barney Britton’s pick this year is the camera that he describes as “close to perfect” for the kind of photography he does. Specifically, two series of 8MP images. At its highest quality setting, the DC produces image files large enough to make high-quality 8 dc2800 inch photographic prints. Lets you record the date and time that the image is captured on the image itself. The 3X digital zoom affords even closer inspection of your subject, with the ability to select zoom ratios in 0.

Revolutionary Breakthrough: AI Trained to Rapidly Create High-Efficiency Perovskite Solar Cells
Researchers in Australia have achieved a groundbreaking feat, training artificial intelligence (AI) to produce solar cells made from the mineral perovskite in a remarkably short period of time. This cutting-edge approach has allowed them to bypass years of human labor and potential errors, leading to the optimization of these cells in just a matter of weeks.
Dr. Nastaran Meftahi, the lead author of the study and a researcher at RMIT University’s School of Science, highlighted that international teams have been in a race to develop perovskite solar cells that are not only cost-effective but also stable enough for long-term commercial use. Thanks to recent advancements, these cells have reached a level of stability where they can be considered for widespread deployment.
Perovskite solar cells are particularly promising due to their potential to outperform traditional silicon-based solar cells in terms of efficiency and cost-effectiveness. However, the challenge lies in finding the optimal combination of materials and fabrication processes to maximize their performance.
To address this challenge, the researchers turned to AI. By training machine learning algorithms on vast amounts of data and simultaneously carrying out experimental work, they were able to rapidly identify the most efficient compositions and fabrication methods for perovskite solar cells. This process significantly accelerated the research and development cycle, which traditionally took years to achieve similar results.
The use of AI has enabled scientists to overcome human limitations and biases that often arise during optimization processes. It can quickly analyze and interpret vast amounts of data, identifying patterns and optimizing parameters that human researchers might overlook. As a result, the AI-generated solar cells exhibited improved efficiency and stability.
The team’s successful AI-driven approach demonstrates the enormous potential of this technology in accelerating scientific discoveries and technological advancements. It may also pave the way for further breakthroughs in other areas of research that require extensive optimization processes.

Microtek Launches ArtixScan 4000tf
New high-resolution scanner with exceptional technologies sets new standards in professional imaging
Rotterdam – Microtek, a pioneer in scanning technologies and a leader in graphic imaging solutions announces the launch of its latest film scanner, the ArtixScan 4000tf, the highest-resolution professional film scanner to hit the market.The ArtixScan 4000tf follows on the heels of the successful ArtixScan 4000t. This upgraded model incorporates built-in FireWire and USB interfaces for fast data transfer and ease of use.
With its 42-bit colour depth, the ArtixScan 4000tf can capture infinitely rich detail from 35mm slides, filmstrips, and Advanced Photo System (APS) film, allowing scans to be printed to pre-press standard at over A3 sizes. The scanner also features an optical range of 4.2 Dmax for delivering superb shadow and highlight details, as well as true optical resolution of 4000 dpi for razor-sharp images without sacrificing detail.
"The ArtixScan 4000tf is designed for users requiring a high-resolution scanner. Customers will be impressed by the ArtixScan 4000tf´s high resolution, sharpening, focus, and colour management features at such a competitive price." Commented Peter Stengel. Sales and Marketing Director."The ArtixScan 4000tf features some exceptional technologies for achieving superior images, including Auto Focus System, Motion Correction Control, and Multiple Sampling."
Features and Benefits:
- The Auto Focus System ( patent pending) adjusts the scanner carriage and APS film holder (instead of the lens position) to automatically achieve the most accurate focus. This robust design keeps the optical mechanical assembly system precisely calibrated at all times, enhancing the scanner´s reliability and ease of maintenance, as well as minimizing scan times.
- Motion Correction Control ( patent pending), was developed by Microtek to address problems with scanner motor deviation arising over the course of the scanner´s life. The scanning module, located at the scanner carriage position and driven by a stepping motor and other guiding mechanics, is subject to deviations for any number of reasons, causing certain tolerances tobuild up. As deviations and tolerances accumulate the scanning module gets increasingly "off" in its position, which if left uncorrected negatively impacts the quality of subsequent scanned images. Through Motion Correction Control, the scanning module is moved accurately to a precise position on a well-calibrated stepping control table, compensating for any misalignments that may occur. The scanning module can thus move smoothly and precisely during the scanning process, registering mechanical steps with ultra-fine precision for superior, accurate scans.
- With Multiple Sampling, the ArtixScan 4000tf is able to reduce the random image noise that adversely affects the quality of scanned images. With this technology, each scanned line is sampled multiple times (the frequency determined by users in 2, 4, or 8 options) to optimize signals, with the samples then averaged out to distill top-quality data. Multiple sampling effectively minimizes signal fluctuation and artifacts, resulting in a purer image output and enhanced optical density range.
- ArtixScan 4000tf provides a fast and easy way to handle film. A 6-frame filmstrip holder and a 4-frame 35mm slide holder are included in every standard package, and an APS film holder is available as an optional accessory. The ArtixScan 4000tf can detect the type of medium being scanned to increase your scanning productivity and shorten your scan times.
Powerful Scanning Software Package adds outstanding value. Included in every ArtixScan 4000tf package are Microtek´s ScanWizard Pro™ TX 6 scanning software and the Microtek Scanner ICC Profiler software.
Microtek´s ScanWizard Pro TX 6 is an advanced scanner controller program that provides many powerful and professional-level features for film and slide scanning. ScanWizard Pro TX 6 uses the LCH colour model, which is a more intuitive way of working with colours according to visual perception and based on the values of Lightness (the "L" in LCH), Chroma (C), and Hue (H). The software also includes the Selective Colour Tool, which is used to perform colour correction to a specific colour range without altering the other colours in an image; and the Filter Tool, which applies special effects such as Blur or Unsharp Masking to your images.
With the Microtek Scanner ICC Profiler, users will be able to precisely calibrate the scanner using Kodak, Agfa, or Fuji´s IT8 targets. The software also generates ICC profiles based on the individual colour "signature" or characteristics of each scanner, so that colours can be reproduced consistently and predictably for optimal results.
Microtek, one of the World’s largest manufacturers of Desktop scanners for PC and Macintosh platforms was founded in 1980 in Taiwan and has always offered high quality products combined with a ‘solution-out-of-the-box’. Microtek offers probably the widest range of flatbed and film scanners that address the needs of most end users. Microtek quality products provide ease of use with value for money.


Dynamic lighting allows users to adjust the brightness and color temperature of tunable white LED luminaires in real-time and freely. Users can use dynamic lighting to provide the most suitable lighting atmosphere for the space or create unique lighting effects to meet particular needs. Since tunable white light applications mainly involve color temperature ranges such as warm white, neutral white, and cool white, some people will refer to such applications collectively as "Human-Centric Lighting" or "Circadian Lighting". As our solution focuses on the commercial application of this technology, we tend to use the term "Dynamic Lighting" to describe our solution. On the other hand, some simple solutions on the market allow users to select a specific color temperature from several color temperatures through a DIP switch and then adjust the light, which does not fall within the scope of our discussion.
Tunable White LED Fixtures
The most apparent difference between Tunable White and regular LED lights is that Tunable White LED lights have three or four leads (Cool White+/-, Warm White+/-) for connection. Tunable White LED lights consist of a pair of warm and cool white LED strings. Thus, unlike regular LED lights with a specific color temperature value (e.g., 3000K, 4000K), tunable white LED lights have a particular color temperature range; the individual color temperature value of the LED strings defines the overall color temperature range available for adjustment (e.g. 2700K - 4000K).
Since Tunable White LED Fixtures require the simultaneous control of both LED strings to control the overall light's brightness and color temperature,Dynamic Lighting requires a slightly more complicated control method than typical dimming. Note that simply tying both strings' positive leads (negative leads) in parallel doesn't produce the expected brightness and color temperature changes. We can see here the surface mounted and recessed downlights are indeed Tunable White fixtures that share the same form factors as dimmable or non-dimmable LED fixtures. That is, the fundamental difference between Tunable and regular LED lights lies in the lighting control.

Reston Hospital Center debuts new real time robotic imaging
Dr. Nicholas Lailas of The Urology Group used the technology to remove a tumor from a patient’s kidney.
When asked about the new imaging technology, Lailas praised the hospital for its willingness to use the innovative technology.
“I am so proud of Reston Hospital Center’s commitment to being at the forefront of this innovative technology. Florescence imaging combined with the new 3-D, HD camera gives the surgeon clear anatomical landmarks to better mark the normal and diseased tissue,” Lailas said in a news release. “We can now perform complex kidney surgery in a more sparing manner using a minimally invasive approach. The imagery that the Firefly upgrade provides us will now allow better visualization of the renal vasculature and differentiate a healthy perfused kidney versus tumor. This will result in improved oncologic outcomes.”
This new fluorescence imaging system, called Firefly, creates an enhanced visual field for surgeons, allowing for more accurate assessments and surgeries.
The new technique incorporates a redesigned 3-D HD camera that is mounted on one of the four arms of the da Vinci Si surgical robot. The specially designed camera and endoscopes allow surgeons at Reston Hospital Center to capture images of tissue and surrounding blood vessels by injecting a unique green colored dye that's activated by near-infrared light. The camera can switch views between standard real time images and images illuminated by the dye.
The technology also allows surgeons to differentiate between malignant and normal tissue as the surgery is performed because cancerous tissue stains less brightly than normal tissue.

FBI: Someone is pointing lasers at airplanes in Kentucky
Someone is shining a laser at airplanes in Kentucky, officials with the Federal Bureau of Investigation said Wednesday.
It’s happened several times over the past few months. Officials said most have happened around Hustonville, Kentucky, between 9 and 11 p.m.
It’s a federal crime, punishable by large fines or imprisonment.
FBI officials said it’s a hazard for pilots, who can be distracted or temporarily blinded by light from a laser beam.
“Individuals often do not realize that traveling over hundreds of feet a tiny, two-centimeter laser beam spreads to become approximately six feet of light that can block a pilot’s vision,” FBI officials said.
Most laser strike incidents happen at flights under 10,000 feet, with the highest percentage being altitude under 6,000 feet.


Seller's Comments and Description:
Real miniature X-Ray camera / camcorder equipped with a special optical CCD lens that will allow you to penetrate a surface object and view what is underneath it. Simply view the images on the built in LCD screen or upload to your PC or laptop via the included USB or connect to your TV, VCR or suitable display if you order the non LCD screen versions and you are ready to see the unseen, this camera has many useful applications, such as detecting concealed items and uncovering document forgeries, however you should not think of this camera as a portable X-Ray machine similar to the ones used in the medical profession as it is not capable of seeing through dense objects, however you will be able to see through certain materials and coverings.
The science behind this amazing camera is quite simple:
Under normal light conditions both visible and infrared light can pass through certain material types covering an object and are then reflected by the objects surface, but the reflected visible light is too strong and saturated for the naked eye to see, however, the clever trick that this camera performs is to filter out the unwanted reflected visible light and allow only the reflected infrared light along with the required visible light to pass making the covered object surface visible.
Due to the nature of this X-Ray camera / camcorder and it's ability to see through certain types of clothing, discretion must be used in its operation, and it should not be used to invade someone's privacy.
You will actually be able to penetrate and see what normally will be invisible to the naked eye.

With every camera being handmade in Sweden, the X1D is actually a special piece of hardware. It’s also apparently a compact mirrorless medium format camera — and that’s a first, actually. The X1D combines Scandinavian sensibility with beautiful performance. Small enough to take anywhere, powerful enough to capture anything.
Hasselblad is one of the most venerable names in photography – its cameras have gone to the moon, after all – but some would argue the value of their $30,000 cameras has been diluted by modern DSLRs and mirrorless cameras, which constantly improve their image quality in much smaller, cheaper packages
To out this camera, Hasselblad turned its focus to size and optical quality. The X1D has a 50MP CMOS sensor, ISO range from 100 to 25,600, and 14 stops of dynamic range. It also shoots in full HD with dual SD card slots, GPS and WiFi. Viewing options for all your future shots would include a 3-inch 920K pixel touch display, or a 2.36MP XGA electronic viewfinder.
With just the 3200 mAh battery loaded, the X1D weighs 725 grams, which is lightweight for a medium format camera.
Your port options are straightforward: a USB-C connector, mini-HDMI and audio in/out. Hasselblad also weather and dust sealed the X1D, so it’s adventure-friendly.
Regarding lenses, Hasselblad launched a new line of XCD lenses with integral central shutters; 45 and 90mm versions are available at launch. Thankfully, the X1D is still compatible with all 12 lenses from the pro H System, but requires an adapter, naturally.
If you’re not familiar with the photography jargon, ‘medium-format’ means the sensor is much larger than even top of the line cameras like the Sony A7R II or Canon EOS 1DX. Those cameras have a 36 x 24 mm chip,. The X1D’s is 50 megapixel sensor is 44 x 33 mm – 68 percent larger.
Given that sensor size is one of the biggest determinants of image quality – not to mention Hasselblad’s history – you can expect this thing to take spectacular photos. It also just looks really pretty.
Specs for the photo nerds
- 725 g / 1.59 lb
- Dust and Weather sealing
- 50 MP 43.8 x 32.9 mm CMOS sensor
5.3 μm pixel pitch
- XGA Electronic viewfinder
- 3-inch rear touchscreen with “smartphone style” UI
- Dual SD Card slots
- GPS (at a later date)
- 14 stops dynamic range, 14-bit color
- 1.7 to 2.3 captures per second
- Native ISO 100 – 25,600
- 60 minute to 1/2000 shutter speed
- 1/2000 flash sync
- 1080p video
- Mini HDMI, Audio In/Out
MSRP? $8,995, which is about right for a medium format camera, especially something from the Scandinavian imaging company.
