Scientists developed a photodiode using a crystalline film composed of lead perovskite compounds with organic chiral molecules to detect circularly polarized light without a filter. It is expected as ...

I have a circuiar polarized filter for my S1 IS. I was told to get a UV Haze filter to cut out pollution. What is the difference? The circular polarized filter cuts out shiny surfaces. Can they be ...

Generation of circularly polarized nonlinear signals from chiral metasurfaces with rotational symmetry under arbitrarily polarized excitation. Left and right circularly polarized light, where the ...

Light corn syrup is used to rotate the plane of polarized light on the stage of an overhead projector. A polarizing filter allows only those photons with electric fields oscillating in a single plane ...

Which polarizer lens filter is best? Photographers of all skill levels love shooting images of nature on bright, sunlit days. But if you’re just starting out with DSLR photography, you may find your ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...

Researchers have revealed that praying mantis (mantids) infected with parasitic hairworms are attracted to horizontally polarized light that is strongly reflected off the surface of water, which ...
