Light polarization creates art, explains mathematical concepts

The polarization of light underpins a variety of recent technological innovations, including 3D cinema and LCDs. In LCDs, tiny electronically controllable liquid crystal elements are sandwiched between polarizers. If, instead, ...

3D digital holograms on smartphones

3D holograms, previously seen only in science fiction movies, may soon make their way to consumer technology. Until now, 3D holograms based on phase shifting holography method could be captured using a large, specialized ...

Metasurface opens world of polarization

Polarization, the direction in which light vibrates, is invisible to the human eye. Yet, so much of our optical world relies on the control and manipulation of this hidden quality of light.

Astrophysicists wear 3-D glasses to watch quasars

A team of researchers from Russia and Greece reports a way to determine the origins and nature of quasar light by its polarization. The new approach is analogous to the way cinema glasses produce a 3-D image by feeding each ...
