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 ...

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 ...

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 ...

One of last year’s Hackaday Prize finalists was the DOLPi, [Dave Prutchi]’s polarimetric camera which used an LCD sheet from a welder’s mask placed in front of a Raspberry Pi camera. Multiple images ...

Three-dimensional holograms may soon make their way into our daily lives. Until now, 3D holograms based on phase shifting holography method could be captured using a large, specialized camera with a ...
