ABSTRACT
This article reports that a team at Germany's Fraunhofer Institute for Silicon Technology is developing a vast-pocket beamer, a portable projector that can be used to display video, text and images onto any available surface. The device is based on a tilting 1.5 mm diameter micro-mirror that builds up a picture pixel by pixel, by rapidly switching its angle and deflecting a laser beam. Each time the mirror is moved, springs pull it back to its original position so quickly that the movement can be repeated, in different directions, several thousand times per second.
