Pocket Sized Mini Projector by Nippon Signal has been a new entrant into the color projector size war. Yes, Nippon Signal has announced Pocket Sized Mini Projector that is about the size of a cigarette case, which is much smaller than the previous one they exhibited at its last exhibition. This one measures a mere 90 x 55 x 20 millimeters, and it makes use of lasers and a pair of MEMS scanners to project an image rather than the more traditional LED. The projector reaches its small size in part by using proprietary optical parts, including a prism lens exclusively made for it.Nippon Signal also swapped a diode pumping solid state (DPSS) laser for a much tinier semiconductor laser to display greens, reduced the dimensions of the MEMS scanner and optimized the layout to fit within its lilliputian confines. The image quality is passable—not even close to movie theater quality, but colors are bright and the resolution is good enough for, say, an impromptu Power Point presentation. When this will be available to the masses, still there is no word, but Nippon Signal informs that it plans on commercializing the prototype quickly.
