Bending the light with a tiny chip: Silicon chip acts as a lens-free projector, may one day fit in cell phones |
March 11, 2014
Traditional projectors -- like those used to project a film or classroom lecture notes -- pass a beam of light through a tiny image, using lenses to map each point of the small picture to corresponding points on a large screen. A tiny silicon chip eliminates the need for bulky and expensive lenses, and instead projects the image electronically by 'bending the light' with no mechanically moving parts.
