cell phone projector

the fraunhofer institute for silicon technology in germany is working on a tiny digital projector small enough to fit in a cell phone. they’ve already built a functioning prototype based on a laser beam flashed at a tilting micromirror that builds up the picture at a resolution of 320 by 240 pixels line by line at high speed. the mirror measures just 1.5 millimeters in diameter, and could be mass-produced on a microchip. via personal techpipeline image © 11/2004 fraunhofer-gesellschaft
