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 ...

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 ...

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 ...

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.

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 ...
