ETENDUE REDUCED STEREO PROJECTION USING SEGMENTED DISK
First Claim
1. A stereoscopic digital image projecting system comprising:
- a light source system energizable to provide polarized illumination having a first polarization state;
a beam splitting system alternately generating first and second light beams having different polarization states from the polarized illumination;
a combining system comprising a polarization beam combiner that combines the first and second light beams into a combined light beam;
a spatial light modulator modulating the combined light beam in a manner consistent with stereoscopic image data to form a first modulated image from illumination in the combined light beam having the first polarization state and to form a second modulated image from illumination in the combined light beam having the second polarization state; and
projection optics configured to project the first and second modulated images.

Abstract
A stereoscopic digital image projecting system has a light source system energizable to provide polarized illumination having a first polarization state and a beam splitting system alternately generating first and second light beams having different polarization states from the polarized illumination. A combining system has a polarization beam combiner that combines the first and second light beams into a combined light beam. A spatial light modulator is used to modulate the combined light beam in a manner consistent with stereoscopic image data to form a first modulated image from illumination in the combined light beam having the first polarization state and to form a second modulated image from illumination in the combined light beam having the second polarization state. Projection optics are configured to project the first and second modulated images onto a display surface.
