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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

It's no secret that there are entire wavelengths of light invisible to the human eye. Animals and insects have eyes that can filter light and polarize it to all sorts of benefits like seeing in the ...
