Abstract

A full color projection system is disclosed herein. The projection system includes a means for generating a first light beam and also a means for generating a second light beam. These means may include either separate light sources 10a and 10b or a single light source 10 and a means for dividing the light source into the first and second light beams. In two examples, the means for dividing may include either a dichroic color wheel 40 or a color splitting prism 52. The first light beam will be modulated by a first spatial light modulator 30a and the second light beam will be modulated by a second spatial light modulator 30b. These spatial light modulators 30a and 30b are preferably, but not in necessarily digital micromirror devices.
