2D micro scanning mirrors are presented which make use of a degressive spring allowing to achieve an optical scan range of up to 112 degrees x 84 degrees, optically. The scanning mirrors are deployed for highly miniaturized monochrome and full color projectors as well as for laser imagers. The projectors allow for projection with VGA resolution at 50 Hz frame rate. The laser imager supports full color SVGA resolution at 30 Hz frame rate. Both, the projector and the imager are based on a single 2D scanner chip and thus could be combined in a single ultra compact system for simultaneous imaging and projection with high depth of focus.
