Imagine a clock where the colors aren’t from LEDs but a physics phenomenon – polarization. That’s just what [Mosivers], a physicist and electronics enthusiast, has done with the Polarizer Clo… ...

EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials ...

That is another case in which half the photons will get through a polarizer, and, as always, those that do so become polarized parallel with the polarizer. You can see how polarizers work by ...

The LCD Circularly Polarized Light Display technology takes a different approach. ... of the polarizer, which contains iodine-infused Polyvinyl Alcohol (PVA), a polarizing absorption layer.

Even in singly polarized light, some minerals betray their identity. In the image above, the brown mineral is hornblende. Most of the other minerals are white (clear), but hornblende is one of the few ...

They found that when polarized light was shone through the nanostructures from certain directions, a range of vivid and easily-identifiable colors was reflected back.
