ABSTRACT:
A projection system is disclosed comprising a light source, a first reflector proximate the light source, a second reflector proximate the light source, a light pipe, a color sequencing device a spatial light modulator and a target. The color sequencing device preferably directs three or more colors onto the spatial light modulator at a time. Some light is reflected from the color sequencing device back through the light pipe and is again reflected at the reflector at the light source before returning to the light pipe and color sequencing device. The brightness of the projection system is thereby increased.
