Patent ID: 8066382

Claim:
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 comprising a rotating segmented disk disposed in a path of the polarized illumination and alternately generating first and second light beams from the polarized illumination, the rotating segmented disk comprising outer segments alternately transmissive and non-transmissive and inner segments radially aligned with the outer segments and each alternately reflective and transmissive, wherein the inner reflective segments correspond with the outer transmissive segments; a polarization rotator positioned in a path of either the first or second light beam and rotating the first polarization state to a second polarization state orthogonal or substantially orthogonal to the first polarization state; a combining system combining 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 onto a display surface.
