High-resolution

Only a small percentage of backlight actually makes its way out through the multiple layers that make up the ubiquitous LCD displays we use today. That may change with the development of new filter technology at the University of Michigan. White light is sent through tiny, precisely spaced gaps on nano-thin sheets of aluminum and is said to result in brighter, higher definition color reproduction. Other benefits of the technology include efficiency gains and simpler manufacturing. Read More

There are many factors other than the megapixel count that affect the quality of images a digital camera will produce – sensor size, lens quality, organization of the pixels, etc. However, consumers often use the number of pixels each dollar buys as a basic measure of value for a digital camera and there has been a steady increase in the “pixels per dollar” for new cameras that roughly follows Moore’s Law. Depending on its cost and when it will hit the market, a new APS-H-size CMOS image sensor developed by Canon could put a bit of a dent in that line with its image resolution of approximately 120-megapixels.

It might be a sad indictment on today’s society but surveillance cameras are an increasingly common sight on city streets around the world. Most of these systems employ a fish-eye lens to capture a wide field of view, but such lenses distort the image and can only provide limited resolution. A new video surveillance system currently being developed by the Department of Homeland Security’s Science and Technology Directorate (S&T) overcomes these shortfalls to provide perfectly detailed, edge-to-edge images that could prove to be of great assistance to law enforcement.

If you’ve ever tried to get that perfect shot of a race car, athlete, wild animal, or any other fast-moving subject, you know how hard it can be - what are the odds that you’ll hit the shutter release button at just the right instant? You could try videotaping it and grabbing a still afterward, but chances are it will be grainy and blurry. It’s a common problem, but it might have just been solved. Medical researchers have developed a digital photographic technique that allows users to simultaneously shoot high-speed (slow motion) video and high-resolution stills, via the same sensor on the same camera.

Instead of light, traditional high-resolution electron microscopes use a particle beam of electrons to illuminate a specimen. However, the particle beam also destroys the samples, meaning that electron microscopes can’t be used to image living cells. Electrical engineers at Massachusetts Institute of Technology (MIT) have proposed a new scheme that can overcome this critical limitation by using a quantum mechanical measurement technique that allows electrons to sense objects remotely without ever hitting the imaged objects, thus avoiding damage.

Forget high definition, AMD claims its ATI Eyefinity multi-screen technology has up to 12 times 1080p resolution, breaking into almost true eye-definition video quality. It's able to power up to six monitors from one card, is Windows 7 ready and positively champing at the bit to unleash the power of Direct X 11. Users can look forward to a much improved immersion gaming experience, or to taking advantage of one huge desktop workspace for better multi-task management, or to being able to keep an eye on breaking Internet news while also playing a game or watching a DVD.

Special sensing technology developed by Raytheon for the US Navy's miniaturized radio frequency system is aboard NASA’s Lunar Reconnaissance Orbiter (LRO), one of two spacecraft hoping to find photographic evidence that the polar regions of the moon contain ice. Until now, man hasn’t been able to confirm if there is ice on the moon because it is thought to exist only in permanently dark patches, or poles, on the lunar landscape – which means we haven’t been able to take detailed photos yet. NASA in particular is interested in determining the extent to which lunar ice exists, if at all, as the agency prepares for future manned exploration and possible habitation on the moon. Read More
