In today's lighting industry rapid development, LED light source with its fixed point, the directional spectrum, high brightness, high purity, cold light, adjustable color temperature, long life and other characteristics, in the smart plant lighting, landscape lighting and lighting, medical lighting in areas such as the rapid development.Although compared with the LED lighting market, LED output value in the field of medical lighting may be tiny, but medical lighting belongs to the medical apparatus and instruments, there are strict regulations and certification requirements, extremely strict in terms of technology, safety rules, compared with the ordinary functional lighting, technology risk bigger, high entry barrier.As the society for health care, medical rehabilitation, green environmental protection and energy saving, LED the medical lighting will set up a new land in the domestic market.
Medical products according to the specific function of lighting specific named dental lamp, head lamp, operation lamp, shadowless lamp, lamp, disinfection lamp and lamp, etc.Medical operation shadowless lamp is an important and indispensable for surgical site lighting devices, it requires both can let doctors best observed at the notch and the body cavity of objects of different depth, size, low contrast;Should be "no shadow" and "light".Traditional shadowless lamp price comparison is widely accepted low halogen tungsten lamp light source, it is easy to appear improper filters, infrared thermal radiation and surgery in patients with regional problems such as drying, and using LED as light source shadowless lamp can solve the above problems.As the requirement of people for medical lighting, LED light source rapid development because of its special advantage, prospects are bright.
By CSA Research available, from 2011 to 2015, Chinese medical lighting lamps and lanterns to the rapid growth of the total exports from $16 million in 2011 to $25 million in 2014, exports increased by almost $10 million.Export to more than $2300 in 2013, the growth rate of 44%, in the first half of 2015, China's medical lighting exports reached $13 million, compared with 2014 increased by 34% in the first half.
Although the entire LED industry products export scale, its export volume has reached $5 billion in 2015 the previous year, medical lighting industry is a "thin" points of the industry, its exports relative to the LED lighting products export vary widely, but with the launch of the new medical reform in health care capacity and establish a basic medical and health system, driven by medical lighting industry will continue to maintain rapid growth.
From 2011 to 2015 years of development, the development of Chinese medical lighting is in a transition period, with the improve of technology and society for the urgent need of medical lighting, medical lighting in our country will realize a full-blown.
Chinese medical lighting according to the light source can be divided into traditional medical lighting lamps and lanterns and LED lighting lamps and lanterns, at present our country exports the global medical products are still in the traditional lighting lighting products, the export of traditional lighting lamps and lanterns in 2011 to $14 million, accounting for about 91% of the total amount of export, only $2011 in 2011 LED medical lighting lamps and lanterns, accounted for only 9%, from 2012 to 2015 in the first half of the LED medical lighting lamps and lanterns of exports has been on the rise, as in the first half of 2015, LED the medical lighting exports accounted for 25%, compared with 2011, LED the medical lighting exports accounted for about nearly tripled.LED medical lighting lamps and lanterns, exports are also growing rapidly, the growth rate of exports in 2013 reached 100%.
CSA Research that LED medical lighting lamps and lanterns of export quotas in our country is lower than the traditional medical lighting products for two things: first, the late start, backward technology, medical lighting for LED products in China r&d begin until 2007.Second, relevant enterprises of our country has entered the LED medical lighting equipment industry barriers is higher, large medical equipment enterprise mostly just incidentally medical lighting products, there are few professional manufacturers.Previous: Industrial design and lighting to accelerate convergenceNext: International lighting fair in Guangzhou


AirMatrix sensors use optical measurement to determine the content of suspended particulate matter in the air. Currently, AirMatrix sensors allow to determine the content of fine particulate matter (PM2.5). A diode emitting infrared radiation and a detector in the form of a phototransistor, have been used in the device. The goal of the detector is to register the radiation reflected from the suspended particles, thanks to which it is possible to assess the content of the particles in the air. The detector converts the information concerning the quantity of the reflected radiation to voltage, proportional to the content of PM2.5 in accordance with the characteristics presented in the picture below.
The correctly constructed electronic system, manages the measuring procedure through activating the light source and detector in planned intervals. The flow of air through the device is forced by a fan, and the airflow is directed by a specially designed duct system. The developed algorithms for processing signals, analyze and convert the sensor’s measurements, ensuring a high reliability of the measurements in terms of the system’s various operations.


Earlier this year Samsung’s Sensor Business Staff Head, Yongin Park revealed that the company is planning for a Isocell 600MP sensor for smartphones. According to Yongin, the sensors will capture the image in 4K/8K resolution with the precision of the human eye (500MP).
The image sensor captures the incoming light and produces a digital image from it. These image sensors contains millions of photosites called pixels (which captures light). And, the total number of these light capturing photosites is termed as Megapixels.
As of now, the largest available image sensor is 108-megapixel. Now it appears Samsung goes ahead with its plan.
On 5th December, a famed tipster, IceUniverse (@universeice) on Twitter claimed that the company started working on the ISOCELL 600MP sensor that is 1/0.57-inches in size. IceUniverse tweeted, “Samsung is really doing 600MP sensors!”, with a confidential investor’s note.
The image also shows the problems that the company might face while working on the 600-megapixel camera sensor.
At present, Huawei P40 Pro+ has the biggest camera sensor that is 1/1.28-inches in size.
However, there’s a catch, that this sensor may not be popping out quickly since Samsung is engaged on decreasing the camera bump. The leaked picture also shows that a sensor this huge would take 12% of the smartphone’s back and will protrude as much as 22mm out of the smartphone’s body. So, it’s hard to expect the 600-megapixel smartphone in the next few years.
Earlier this year, Park also revealed that the upcoming ISOCELL 600MP sensor (ISOCELL600) wouldn’t be simply restricted to smartphones. It will likely be used in other fields too such as autonomous autos, IoT, and drones.
Park additionally laid out the Samsung’s plan of developing different sensors in his editorial including an image. The sensor can also be used in the analysis of skin cancer and also serving a function within the agricultural discipline. And that’s not it, the company is also working on different sensors that will register smell or tastes.
The latest launched smartphone, Samsung Galaxy Note 20 Ultra and Samsung Galaxy S20 Ultra both having 108-megapixel main sensor. The sensor used was ISOCELL HM2 with 0.7um pixel size and optical format 1/1.52″. Another 108MP image sensor is ISOCELL HM1 with 0.8um pixel size and optical format 1/1.33″.
600-megapixel smartphone seems be a bit funny at present. However, it will solve many other problems and will be the biggest innovation if Samsung succeeds in this.
What do you think about this?

We report vertically illuminated, resonant cavity enhanced, graphene–Si Schottky photodetectors (PDs) operating at 1550 nm. These exploit internal photoemission at the graphene–Si interface. To obtain spectral selectivity and enhance responsivity, the PDs are integrated with an optical cavity, resulting in multiple reflections at resonance, and enhanced absorption in graphene. We get a wavelength-dependent photoresponse with external (internal) responsivity ∼20 mA/W (0.25A/W). The spectral selectivity may be further tuned by varying the cavity resonant wavelength. Our devices pave the way for developing high responsivity hybrid graphene–Si free-space illuminated PDs for optical communications, coherence optical tomography, and light-radars.

My primary interest is in the study of optical methodology, biomedical optics, which is applicable to the biological and medical uses, and in the study of the physics on the biomedical optics. In particular, I am interested in the time-resolved spectroscopy and the correlation spectroscopy from the single-molecule level to the individual tissue level of small animals or human. I am currently focused on the tissue optics in a near-infrared region over 1 μm wavelength to obtain new information such as the water and structure of tissues. Since this region is essentially free or negligible from the heme absorption, this region could be used for a new optical window of the tissue, where the structure and dynamics are directly monitored. Further, the quantitative measurements of the extrinsic probe signals, such as fluorescence and scattering, are possible. I am expecting that this near-infrared wavelength region is key of yielding the detail information of complex hierarchical biological system.

Principles of Lasers and Optics by Chang, William S. C.
CAMBRIDGE UNIVERSITY PRESS | 05 January 2012
Hardback | 260 pages
Principles of Lasers and Optics, first published in 2005, describes both the fundamental principles of the laser and the propagation and application of laser radiation in bulk and guided-wave components. All solid state, gas and semiconductor lasers are analysed uniformly as macroscopic devices with susceptibility originated from quantum mechanical interactions to develop an overall understanding of the coherent nature of laser radiation. Analyses of the unique properties of coherent laser light in bulk and guided-wave components are presented together and derived from fundamental principles, to allow students to appreciate the differences and similarities. Topics covered include discussions on how laser radiation should be analysed, the macroscopic differences and similarities of various analyses, special techniques, types of lasers and setting up laser analyses. This text will be useful for first-year graduates in electrical engineering and physics and also as a reference book on analytical techniques.


Future Proofing Strata Titling
At present, Lidar (light detection and ranging) is playing a transformational role in surveying and mapping. Lidar could be identified as a remote sensing method that uses light in the form of a pulsed laser to measure distances to surfaces. Amongst the many benefits this technology offers, the ability to collect millions of data points fast and accurately, day or night, with minimum human resources and few control points, stands out as its most pioneering trait. Moreover, the additional data points collected that you may not need could be utilised in other applications as well. It has continuously proven over time as a productive technology within many industries, e.g., civil engineering, construction, transport, and mining.
The laser scanning technology could largely contribute efficiencies in strata titling. Currently, cadastral surveyors utilise distance laser measurers to verify strata plans against what is built. The handheld laser scanners effectively replace distance laser measurers and offer a better experience and output for titling purposes. The handheld scanners also provide the ease of collecting data by simply walking in and out of buildings. This allows laser scanners to have the ability to depict a complete picture which would yield more comprehensive space measurements. In addition, laser scanning would enable us to create 3D strata plans, and the inevitable adoption of digital twins and 3D cadastre by land registries has led to distance laser measures being ineffective.
However, there is a twist in the scenario in terms of using the output of laser scanners. Laser scanning is considered to be very efficient, but there is a bottleneck. Converting the output of laser scanners; point clouds, to maps and models is often monotonous and time-consuming. It is estimated that the conversion process takes up to 16 times longer than regular scanning. Therefore surveyors are reluctant to use laser scanning in strata titling as the considerable conversion time outweighs the efficient data collection.
We at Faramoon, aim to eliminate this bottleneck with the development of Scan to BIM technology that would drastically reduce the conversion time. With this innovative technology, we possess the ability to transform point clouds to plans/3D models 100 times faster than manually modelling by an operator. Even better, it fits perfectly in line with strata plan requirements as it can generate 2D plans. Furthermore, architectural components such as walls would be extracted automatically, providing the opportunity to define title boundaries efficiently. Does all this sound interesting? Want to give it a go?
We offer a free trial to improve your current strata titling process or future proof it. Either way, we have a solution. Find yours now by contacting hello@faramoon

What do your cable TV, internet network and landline all have in common? They are all most likely supported by fiber optics. Fiber optics are strands of glass fibers that are designed to provide long-distance, high-performance data networking and telecommunications, but what exactly are they?
What are fiber optics?
Fiber optics are pretty amazing. In fact, they are so amazing that the man who designed them received the Nobel Prize in Physics in 2009 for his work. Optical fibers are incredibly thin strands of glass or plastic. In fact, one optical fiber is one-tenth the width of a human hair. A fiber optic cable is made up of anywhere from two optical fiber strands up to several hundred, all housed inside a single cable.
How do fiber optics work?
Fiber optics use photons, or light particles, to transmit digital signals. The light is directed between the optical fibers through the use of shallow angles, which cause the photons to bounce back and forth down the cable. The core of the cable is the part that transmits the photons, while a second layer of glass, called the cladding, keeps the light from escaping. The capacities of fiber optic cables is staggering. When used for telephones, for example, each optical fiber can carry 25,000 calls, so a cable made of hundreds of strands has the capacity to carry millions of calls.
How are fiber optics made?
Optical fibers are made through processes similar to those used to create other glass products. To create an optical fiber, a glass rod is heated to the melting point and then pulled into a thin fiber of about 125 micrometers. Each fiber is wound together with other fibers to create a thicker strand. The fibers are then encased within a protective polymer buffer or jacket.
What are fiber optics used for?
Most people are not aware of how universal fiber optics really are. In fact, any part of your life that includes a data network or telecommunications is most likely supported by fiber optics. As a company that offers fiber optic installation in MT, here are just a few of the ways we know our customers are using fiber optics every day:
- Networks: Computers once used telephone lines to connect, but fiber optic cables carry far more data far more quickly compared to these older styles of electronic transmission.
- Broadcasting: When there were fewer households with TV and only a handful of channels, electromagnetic waves were used to transmit signals. But to provide millions of homes with thousands of channels, TV providers switched to optic fibers to provide digital broadcasting.
- Medicine: Fiber optics support medical devices that help doctors look inside human bodies without cutting them open.
- Military: Fiber optic cables are inexpensive, high-capacity, lightweight and robust against attack, which makes them secure and perfect to support high-tech military operations.
Fiber optics support much if what we do in the modern world. If your business depends on fiber optics and you’re looking for fiber installation in MT, be sure to call on the experts at Tech Service Company!

Embedding Fiber Optical Sensors in FRP-Hybrid Materials
Proceedings of the International Conference on Composite Materials (ICCM2023)
by J. Pettersson; C. Sterner; H. Dykhoff (RISE)
The presented work includes development and verification of techniques for embedding fiber- optical sensors in Fiber Reinforced Polymers (FRP) and Aluminum hybrid materials for Structural Health Monitoring (SHM) purposes. The fiber-optical sensors both survive the manufacturing process of the FRP-Hybrid material and achieve sufficiently strong bonding to the material matrix. Mechanical tests have been performed to characterize the performance of embedded fiber-optical sensors for obtaining strain data under both static- and cyclic loading. Further, the fiber-optically read strain data is comparable with the strain readings from surface-mounted extensometers and strain gauges. Embedded fiber-optical sensors could monitor up to 1,5 – 2% strain in quasi-static tensile tests. During cyclic tests at low load, within the linear elastic region, the embedded sensors provided strain data for the entire testing cycle (18 000 cycles). At high cyclic loading, above the linear elastic region (300 MPa, 5 Hz), the embedded sensors provided strain data for 5000 cycles. This work has shown that embedded fiber-optical sensors can be used for Structural Health Monitoring of mechanical components.

Digital Video Processing with HD CCTV: Noise reduction
Digital Video Processing with HD CCTV: Noise reductionIn this post I examine some of the sophisticated technology used in digital high definition CCTV cameras, including a the powerful underlying SOC electronics, and the similarities with audio noise reduction in audio, as used in amateur radio.
Noise reduction in HD CCTV
I read very widely and like to see or create connections between apparently disparate ideas and technologies. From an earlier post on working with a Pentax lens I have, I read about the image processing abilities of some Pentax lenses.
Pentax/Richo have an award-winning image processing system, PENTAX Atmospheric Interference Reduction (PAIR). http://www.ricoh.com/fa_security/security/pair/ The results are amazing:
From a first reading, the processing seems to be done in the lens itself, something that had me mystified as to how such spectacular results are possible with just optics. However, on closer reading, the output of the camera is fed into the lens and the main output is from the lens. As such, the lens has on-board processing of the captured images, making such image processing more plausible, compared to doing it with optics as I first thought. The connection are shown:
The lenses are expensive, for CCTV lenses, at about $10,000. Having realised the PAIR system uses the raw images from the camera, then it is easier to see how it might work; it is very difficult to find technical information on the PAIR system, secrecy can be better than patents for protecting intellectual property, something I have experienced myself during my career with technology transfer.
On the other hand, Texas Instruments, who make a very sophisticated system on a chip (SOC), video processing system (VSP), has an interest in telling the world of its possibilities, in order to sell more chips; even a Wiki: http://processors.wiki.ti.com/index.php/Category:DaVinci.
The TI Da Vinci SOC is essentially a video camera on a chip plus powerful VSP. The block diagram of a "reference design" networked camera: http://www.ti.com/lit/wp/spry224/spry224.pdf
With this SOC, it is possible to produce very powerful CCTV cameras at low cost. I purchased such a camera, with a 2K UHD sensor, but no lens, for about $170 from http://www.aliexpress.com/. It was purchased to investigate DATV over networks and UHD DATV, subjects of earlier posts. However, with the DSP, there are other possibilities. Taking the lid off the camera revealed a very simple construction. The main SOC is obscured by a heatsink, while the other chips were memory or auxiliary.
Low-light noise is a bug-bear of CCTV security systems. Using the TI SOC, noise reduction is possible: http://www.ti.com/lit/wp/spry224/spry224.pdf (Nov 2012, so close to state of the art)
Looks familiar to Pentax PAIR technology? TI's solution is to put the DSP in the camera and use conventional lenses, whereas Pentax's solution is to put the DSP in the lens. TI go on to discuss the algorithms.
Amateurs are fairly familiar with noise, with much of it being random, likewise with video. TI identify two techniques to remove noise: spatial and temporal filtering (see pdf for details). The essential approach is to compare a number of frames (typically collecting 25 or 30 frames per second), with little motion. What is in one frame, but not another is usually noise and can be removed. This is very similar to noise-cancelling with audio and radio where two different sources (two antenna, two microphones) are used and the differences discarded as noise.
Temporal filtering is more complex as it is used with moving images and needs to differentiate noise between frames as well as motion between frames; a two level system with different time regimes.


My well being insurance must cover me when I need to have it. Close loopholes that can leave me huge surprise medical bills. Prime high quality optics, dependability, and convenience of use are just some of the reasons that buyers choose Canon digital cameras. Our favourite digital cameras are from Sony and Nikon, nevertheless you are presenting some really inexpensive options here. Canon cameras are divided into two broad product lines, Canon EOS for their SLR models, and Canon PowerShot for their point & shoot designs. Digital cameras have replaced Film cameras and Digital SLR Cameras have replaced Film SLR Cameras. And but a year later, Canon released yet another iteration of its Canon EOS Rebel series.
Whilst the G5X does not bring several new performance features to the table, it continues where the G7X left off and should prove to satisfy a lot of seasoned photographers looking for a fixed-lens compact camera. Let’s take a rapid look at how the line has evolved and and how far Canon’s entry level cameras have come. Only the Canon t4i involved a main upgrade with a new image processor, but there isn’t much left to increase.
Canon introduced the Rebel line of SLR digital cameras in 2003, another renowned line of cameras. The Canon t2i supplied a handful of improvements more than the original Canon EOS Rebel camera. The lengthy-awaited Canon 70D comes packed with a groundbreaking new technology – Canon’s Dual Pixel CMOS AF method – that provides on-chip phase detection autofocus at every single single pixel. If you’re looking for a low barrier of entry into the DSLR planet, the Canon Rebel T5 is a great place to commence. I ended up buying a Sony so that I could use the old Minolta film lenses with it. I’ve been quite happy, at least until I had to send it off to the factory for repair. Mr. B wants to buy a Nikon DLSR and use the lenses from the F3 with it (if it has the bayonet mount). Canon at the moment makes digital cameras at its Oita Factory in Japan for each the SLR and customer markets. Subsequent I focused on newer digital SLR cameras, created inside the previous two years.
Definitely, for the easiest operation a Smart Auto or Intelligent Auto Mode is good as it enables the camera to choose the appropriate settings with no the photographer obtaining to figure it all out. The final non-EOS based SLR camera made by Canon, the Canon T90 of 1986, is widely regarded as the template for the EOS line of camera bodies, even though the T90 employed the older FD lens-mount common. Using just the camera and pop-up flash, you could remotely trigger a whole set of flashes to take intricately lit portraits and images. Optical zoom is superior in high quality, but digital zoom can be beneficial with no degrading image top quality in smaller print sizes (4×6). Canon’s initial digital compact camera was the RC-701, sold for the initial time in July 1986.
Several point and shoot cameras give automated controls to customers that aid adjust exposure, shutter speed, and/or white balance to capture greater shots despite alterations in lighting and a lot more difficult conditions. PowerShot fixed lens cameras that are in the $500-$1,000 range are higher-finish models that produce outstanding image high quality and quickly performance levels. I have an old film camera that possibly expense a couple hundred dollars 20 years ago, but unfortunately the lenses are not compatible with new digital SLR cameras. With a 24.two megapixels sensor, the Canon T6s produces outstanding pictures, with tons of detail and precise colors.


China Industrial Laser Challenges
In the view of Western industrial laser processing system manufacturers, China is the largest single market for its products and may become an important competitor in its own market in the near future.
In 2016, China's industrial blue laser materials processing equipment market was about $ 3.8 billion, with an average annual compound growth rate (CAGR) of 12.51% over the past five years. The growth rate in 2017 is expected to be about 22%, the value will reach 4.6 billion US dollars. From this point of view, the global market for materials processing in 2016, the total market volume of about 12.6 billion US dollars, while the Chinese market reached the global laser materials processing equipment system revenue of one-third. Global laser materials processing system popular markets include smart phone manufacturing, aluminum deep processing of metal sheet cutting, electric vehicle batteries and display and so on.
In 2016, China's industrial laser system imports amounted to 640 million US dollars, compared with 2014 up to nearly 1 billion US dollars of imports fell by about 30%. The downward trend in this import ratio is expected to continue to decline by 18% in 2017. The figure illustrates the relationship between China's laser system exports and imports from 2010 to 2017. By the end of 2017, China's industrial laser system exports may reach an average compound annual growth rate of 21.9%, and since 2010, China's industrial laser pointer system imports showed a -3.4% annual compound growth rate.
From another point of view, China's materials processing laser system suppliers in the past five years, the average annual compound revenue growth rate of 16%. According to the news, these enterprises have about 150 enterprises in the annual revenue of more than 5 million US dollars. These domestic suppliers since 2010, the average annual compound growth rate of 22%, estimated in 2017 will reach 480 million US dollars. Most of these systems are exported to South Korea, Taiwan and Vietnam, as well as India and Malaysia and other manufacturing industries rapid development of the market.
China's laser materials processing system exported to the United States and Europe, is currently in its infancy, because exports to these markets also need to solve some security and reliable standards and other issues. This is particularly difficult in Western countries, Western countries to respond to fast service and accelerate the replacement of parts supply requirements have been formed. Chinese system vendors are beginning to realize that the primary focus of US and European buyers is the reliability of the equipment, not the price of the system.
The use of fiber lasers as a source of light in many industrial green laser systems on the market helps to ease service and reliability issues. Fiber lasers are energy-efficient, easy-to-replace and easy-to-maintain devices that are cost-effective in manufacturing environments. Long-term reliability is the main driving force for upgrading fiber laser mounting to one-third of all industrial laser sales.
The Chinese government also hopes to make breakthroughs in intelligent manufacturing, improve supply quality and efficiency, stimulate actual demand, strengthen new growth momentum, focus on manufacturing innovation and information and manufacturing technology integration, enhance information technology and high-end equipment, promote robotics and intelligent systems The development of all this directly or indirectly related to industrial laser technology. If these goals are achieved, it is expected to enhance the competitiveness of Chinese enterprises in the global market.
Even with the government's encouragement and support, China's laser system manufacturers are facing some obstacles, it is difficult to achieve more than 5% of the average annual compound growth rate. First, the selling price advantage is challenged. Faced with strict international standards of kilowatt-class cutting welding system competition, and get the appropriate after-sales service support, the Chinese system manufacturers may no longer have the existing sales price advantage. In addition, improved industrial red laser light technology (UV lasers, ultrafast lasers and high power / high beam quality diode lasers) from other global suppliers have entered the international market and have been far ahead of Chinese companies.
However, leading Chinese manufacturers are beginning to realize changes in the market environment. With the R & D spending plan, Chinese manufacturers can take advantage of world-class equipment to enter the market that is profitable and difficult to access at present, so as to achieve the goal of providing high value-added laser equipment suppliers by the Chinese government.


Research on the Method of Traffic Flow Detection at Traffic Junction Based on Halcon
(Xi’an Highway ResearchInstitute, Xi’an 710065,China)
Abstract: In this paper, a video image processing detection algorithm at traffic intersection was designed using Halcon computer vision algorithm library in order to provide a solution for traffic flow detection in intelligent transportation. Application of the moving target detection method based on hybrid Gaussian background model was studied, and the basic algorithm principle was analyzed to select key functions in Halcon for the detection algorithm in HDevelop development environment. In the verification stage, continuous 500 frames of images were processed and analyzed. The result showed that this algorithm could capture moving vehicle targets in the traffic road quite effectively at an average processing speed of 5.8ms per frame, which could meet the real-time requirements.
key words: intelligent transportation; traffic flow detection; machine vision; Halcon

In this module we have all the functions and data structures needed to describe the projection of a 3D scene space onto a 2D image plane.
In computer vision, we can map between the 3D world and a 2D image using projective geometry. The module implements the simplest camera model, the Pinhole Camera, which is the most basic model for general projective cameras from the finite cameras group.
The Pinhole Camera model is shown in the following figure:
Using this model, a scene view can be formed by projecting 3D points into the image plane using a perspective transformation.
- \(M'\) is a 3D point in space with coordinates \([X,Y,Z]^T\) expressed in a Euclidean coordinate system.
- \(m'\) is the projection of the 3D point \(M'\) onto the image plane with coordinates \([u,v]^T\) expressed in pixel units.
- \(K\) is the camera calibration matrix, also refered as the instrinsics parameters matrix.
- \(C\) is the principal point offset with coordinates \([u_0, v_0]^T\) at the origin in the image plane.
- \(fx, fy\) are the focal lengths expressed in pixel units.
The camera rotation and translation are expressed in terms of Euclidean coordinate frame, also known as the world coordinates system. This terms are usually expressed by the joint rotation-translation matrix \([R|t]\), or also called as the extrinsics parameters matrix. It is used to describe the camera pose around a static scene and translates the coordinates of a 3D point \((X,Y,Z)\) to a coordinate sytstem respect to the camera.

Eye Surgical procedure has become a mainstream technique of vision adjustment, as well as this short article will certainly clarify the benefits and also disadvantages of three different methods being provided to the medical consumer.
Lasik Eye Surgical treatment
LASIK is the phrase for Laser-Assisted In Situ Keratomileusis and is an eye surgical system which completely deals with vision by eliminating a slim layer of the cornea. This treatment functions best on individuals with moderate to high levels of myopia (nearsightedness), low to modest levels of hyperopia (farsightedness) as well as astigmatism associated with nearsightedness, as well as who have thick corneas. It is the most popular surgical vision correction approach.
Individuals with normal eye view see items plainly because images are brought right into a right focal point by the cornea and also lens of the eye. Ideally, the cornea's curvature is uniformly matched to its length in a regular eye. People with astigmatism, myopia or hyperopia have off-and-on shaped corneas, so the things seen are not focused properly. LASIK adjustments corneal shape by exact elimination of corneal tissue, and also by doing so fixes the eyes' concentrating power.
There are, nevertheless, risks to LASIK eye surgical treatment.
There is a remote chance of complete loss of vision. If this takes place, it is typically due to the fact that the client had a pre-existing problem which should have precluded the surgical treatment in the first place, such as pregnancy, cataracts, joint inflammation, diabetes, glaucoma, or lupus. People with huge students are likewise bad prospects for LASIK. Dry eye disorder will be exacerbated by this procedure.
A couple of clients whine that they permanently see "ghost" pictures, have obscured vision, diminished contrast and also negative night vision. When LASIK was first presented, 5% of people had post-operative grievances; however, refinements in the treatment have actually triggered this rate to go down to much less than 1% if LASIK is performed by competent experts and patients are appropriately screened prior to surgical procedure. If troubles do happen, they could often be resoved by a retreatment.
FDA has accepted LASIK laser eye surgical treatment since 1998. While there are a lot of satisfied clients, there are however no long-term researches concerning its results. Understand the limitations and the threats of LASIK eye surgery before you sigh for the treatment.
Though less well known, these small implants could boost vision in individuals with moderate to modest myopia without the risk of permanent eye damages inherent in the cells removal strategy of LASIK. Get More Information Intacs are semi-circular disks dental implanted in the cornea which stretch it to assume a flatter form. Though somewhat less precise compared to LASIK, they are removeable and also changeable, so if the client has an unforeseen over- or under-correction, the implant could be removed and also another of a different size placed to acquire the desired adjustment. The implants are located at the edge of the cornea, so the main aesthetic location is totally intact and also intact, and also the strength of the cornea is undiminished, making it a better option for pilots and also those that engage in get in touch with sporting activities where eye injury is an opportunity.
Intacs are unsuitable for serious nearsightedness and more than small astigmatism (1.00 diopters), as the cornea can only be stretched so far. If the Intacs are gotten rid of, vision go back to its preoperative degree. Besides vision modification, Intacs are additionally utilized to treat keratoconus.
Intacs are FDA authorized and also One Decade researches have actually revealed no major problems with Intacs and very few individual problems; nonetheless, due to the fact that the treatment takes more training compared to LASIK, there are less eye surgery clinics offering it. Nonetheless, the Intacs website gives a checklist of practitioners in each state, too a couple of in Canada, Europe as well as Mexico.
Since many people do not helpful site want to risk LASIK and also Intacs could not assist those with severe vision problems, intraocular lens implants (IOL) are a brand-new choice authorized by the FDA in 2004 to correct modest to extreme nearsightedness. The Artisan lens, manufactured by Ophtec, resembles the kind of lens implant made use of to bring back vision complying with cataract eye surgery.
The brand-new IOL, called the Artisan, is planned for only people who have 2.5 diopters or much less of astigmatism.
The man-made lens does not replace the all-natural lens, but is put in front of it. The major issue found with the dental implant was the steady loss of endothelial cells in the corneas of people who received the implants. The endothelium is a layer of cells that line the undersurface of the cornea as well as are essential in maintaining the cornea clear. A three-year study revealed a consistent stable loss of endothelial cells of 1.8 percent a year. At this point, no person could predict whether this loss will continue at the same rate forever, and even its impact on corneal function.
To minimize long-lasting results of the gadget on the corneal endothelium, the FDA is calling for that the brand-new lenses be labelled to specify that they ought to only be dental implanted in individuals whose corneal endothelial cells are thick adequate to withstand minor cell loss.
Much more significant problems were couple of: retinal detachment (0.6%), cataract advancement (0.6%), and also corneal swelling (0.4%). The FDA is needing Ophtec to perform a five-year follow-up survey of its dental implant clients to better analyze the post-surgical incidence of cataract growth, retinal detachment and also various other ocular diseases.
The Artisan lens is intended to be a long-term implant.Though it could be gotten rid of surgically, vision may not constantly go back to what it was before obtaining the lens. Because it does not affect astigmatism, clients with this issue may still call for glasses.

Probing Matter with Attosecond Photo-Electron Wavepackets
Electronic processes and electron-driven reactions in atoms, molecules and condensed systems can proceed very rapidly, with relevant time-scales in the attosecond (1 attosecond=10-18 s) regime. When activated by the photoabsorption of extreme-ultra-violet attosecond laser pulses, the electron dynamics can be probed in real time by employing the coherent optical field of an additional infrared laser to mark time during the system’s evolution. While temporal resolutions on the order of 10 attoseconds have been demonstrated in such measurements, the physical insight which can be directly gleaned from these experiments has been limited, relying on extensive numerical simulations for interpretation. Now, a team from the University of Virginia and the Ohio State University has demonstrated a new technique that utilizes quantum interference in attosecond photoionization to directly reveal explicit information on an electron’s local environment, captured within a brief time interval (~ 1 femtosecond) following its emission. Initially applied to investigate the effects of electron correlation within atoms, the method should be applicable to molecules, and perhaps condensed systems as well.

An optical filter is an optical component that selectively transmits light in a specific range of wavelengths, namely colors, and absorbs the rest. Generally, an optical filter selectively transmits only long (longpass filter) or short wavelengths (shortpass filter), or blocks both long and short wavelengths through a wavelength band (bandpass filter).
Optical filters are used in cameras, various optical instruments, and color stage illumination, and in astronomy to limit the light transmitted to the spectral band of interest, and are essential in fluorescence applications such as fluorescence microscopy and fluorescence spectroscopy.
ILUCO produces a wide range of filters ranging from simple color glass filters to narrow bandpass filters with high strength coatings.
|IR Filter||Infra Red Cut/Pass|
|UV Filter||Ultra Violet Cut/Pass|

A quartet of false-color, composite images show the dance of Saturn's southern lights in data obtained by NASA's Cassini spacecraft. This image is among the first images to be released from a study that extracts auroral emissions out of the entire catalogue of images taken by Cassini's visual and infrared mapping spectrometer.
In this image constructed from data collected in the near-infrared wavelengths of light, the auroral emission is shown in green. The data represents emissions from hydrogen ions in of light between 3 and 4 microns in wavelength. In general, scientists designated blue to indicate sunlight reflected at a wavelength of 2 microns, green to indicate sunlight reflected at 3 microns and red to indicate thermal emission at 5 microns. Saturn's rings reflect sunlight at 2 microns, but not at 3 and 5 microns, so they appear deep blue. Saturn's high altitude haze reflects sunlight at both 2 and 3 microns, but not at 5 microns, and so it appears green to blue-green. The heat emission from the interior of Saturn is only seen at 5 microns wavelength in the spectrometer data, and thus appears red. The dark spots and banded features in the image are clouds and small storms that outline the deeper weather systems and circulation patterns of the planet. They are illuminated from underneath by Saturn's thermal emission, and thus appear in silhouette.
The images that make up the composite were obtained on May 24, 2007.
