Abstract
A reliable micromirror device for imaging applications is presented. The device includes a projection lens assembly and an array of micromirrors for fast and efficient color separation and projection. Each of the micromirrors simultaneously receives a plurality of light beams. The position of a micromirror in the array of micromirrors is adjustable such that the micromirror selects one of the plurality of light beams to direct toward the projection lens assembly. Each micromirror also has an 'off' position where none of the reflected light beams is directed toward the projection lens assembly. An image is formed when each of the micromirrors in the array either directs one of the light beams toward the projection lens assembly or is turned 'off.' The device may include a total internal reflection prism assembly that separates the light beams for improved contrast.
