Comment Lasers project decent video + games! (Score 3) 122
We have been projecting video-like images with lasers for several years. Since laser images are inherently vector based, we refer to these types of images as raster images. Yes, obvious and redundant. BUT, you must remember that we are using vectors to emulate the other medium. So I suppose it is not such a false nomenclature when you remeber that X-Y TV's get that extra vector prefix!
The current version of Pangolin's QM2000 (link in earlier post) supports direct projection of any video source -- even a composite input! We routinely project video from a live camera feed at our performances... perhaps those in Pittsburgh this weekend will get a demonstration.
Althought the best scanners today are projecting 50k points per second, this is measured using a special calibration frame. Since the X scanner is only following a sawtooth waveform, it is possible to more than double this speed. The Y scanner is basically relaxing to provide the vertical waveform. The color control comes from the PCAOM, which modulates the color at >120Khz. The results are stunning. Pangolin's website has great infomation on these techniques:
Real Time Video Raster Info
Thus, ANY video or GAME for that matter could be projected -- but the unique quality of laserMAME is that the format stays entirely in the vector realm, and infinite scalabilty is achieved.
