The single spiral image is an off-angle scanning electron microscope image of a fabricated circular polarizer. A circular polarizing camera could help warfighters filter out unwanted light. Technology ...

Many people know how helpful polarized sunglasses are in cutting the glare coming off water on a sunny day. But a filter that could let people see — or block out — all the polarizations of visible ...

Polarizing filters have long been used as a tool to reduce glare, minimize reflections, and improve the color of the sky in photographs by absorbing certain wavelengths of light before they hit the ...

Researchers have developed a metasurface attachment that can turn just about any camera or imaging system, even off-the-shelf systems, into polarization cameras. The attachment uses a metasurface of ...

Light is just a wave, and the wavelength of light determines its color and determines if it can cook food like microwaves, or if it can see through skin like x-rays. There’s another property of waves ...

Light polarization is an interesting phenomenon that is extremely useful in many situations… but human eyes are blind to detecting any polarization. Luckily, [David] has built a polarization-sensitive ...

Algorithms exploiting light’s polarization boost resolution of commercial depth sensors 1,000-fold. http://news.mit.edu/2015/algorithms-boost-3-d-imaging-resolution ...

3D holograms, previously seen only in science fiction movies, may soon make their way into our daily lives. Until now, 3D holograms based on phase shifting holography method could be captured using a ...

Inspired by the visual system of the mantis shrimp-researchers have created a new type of camera that could greatly improve the ability of cars to spot hazards in challenging imaging conditions.

How do polarization technologies work? Advances in imaging technologies. Imaging sensors have undergone many advances in the past two decades. At the heart of it all was enabling better pictures that ...
