Vest pocket projector uses micromirror technology

December 14, 2004 Researchers at the Fraunhofer Institute in Germany have built a prototype pocket projector with a tilting micromirror that builds up the picture line by line for legible graphics and text. Future models are likely to be no larger than a cube of sugar and could be incorporated into a mobile phone, allowing the miniature projector to be always on hand to present PowerPoint slides to a small group of customers or for quickly consulting an online journal. It could also provide useful orientation in unfamiliar towns by projecting a street map onto the wall of the nearest building.
