A study of Real-image-projector by using the Transmissive-retro-reflectors

Abstract

We made the optical device was composed of a pair aggregates of the rectangular micro mirrors. The projected real image was focused by this transmissive-retro-reflectors. Then we researched on this device. The maximum resolution was 2 point/mm. The maximum projection range was about 600mm. The effective view angles are +/-19 degrees in vertically, +/-15 degrees in horizontally..
