Patent ID: 7871165

Claim:
A system for viewing stereoscopic images, comprising: polarized glasses worn by a viewer for viewing stereoscopic images formed on a display surface, wherein a polarized filter for a first eye transmits polarized light that is orthogonal to polarized light transmitted by a polarized filter for a second eye; and a stereoscopic digital image projector comprising: an illumination system comprising: first and second polarized light sources, wherein the first and second polarized light sources have orthogonally disposed polarization axes; and a polarization beamsplitter disposed to direct light of both the first and second polarizations along a common illumination axis; a controller system that alternately energizes the first and second polarized light sources to provide illumination of one polarization at a time; a single MEMS spatial light modulator for alternately modulating the light beams of the first and second polarizations on the common illumination axis; and projection optics in the path of modulated light from the MEMS spatial light modulator and directing the light onto the display surface.
