A video projector the size of a sugar cube

Article Summary

September 19, 2006 Miniaturised projection systems have been spoken about for a long time, but with several viable technologies seemingly close to market, the day when you can carry a video projector at all times, just in case you need it is close. In February, we wrote about the matchbox-sized PVPro projector and now news from Faraunhoffer suggests that not-too-far down the track your handheld, digital camera, portable media player or phone might have a projector built-in. That’s the promise of a new technology for projectors that does not use conventional micro arrays, instead containing just a single mirror that can be rotated around two axes. Researchers at the Fraunhofer Institute for Photonic Microsystems IPMS in Dresden and the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena have developed an alternative to micro mirror arrays and the result is a projector the size of a sugar cube.
