摘要： A digital cinema projection apparatus having an illumination source with a first etendue value for providing polarized polychromatic light. A first lens element lies in the path of the polarized polychromatic light for forming a substantially telecentric polarized polychromatic light beam. A color separator separates the telecentric polarized polychromatic light beam into at least two telecentric color light beams. At least two transmissive spatial light modulators modulate the two telecentric color light beams. There is an etendue value associated with each spatial light modulator. The etendue value is within 15% or greater than the first etendue value corresponding to the illumination source. A color combiner combines the modulated color beams along a common optical axis, forming a multicolor modulated beam thereby; and a projection lens directs the multicolor modulated beam toward a display surface.

摘要： A stereoscopic digital image projecting system has a light source system providing polarized illumination having a first polarization state and a beam splitting system with a rotating segmented disk in the illumination, alternately generating first and second light beams, the rotating segmented disk having outer segments alternately transmissive and non-transmissive and inner segments radially aligned with the outer segments and alternately reflective and transmissive. A polarization rotator in a path of either the first or second light beam rotates the first polarization state to a second state orthogonal to the first. A combining system combines the first and second light beams into a combined light beam. A spatial light modulator modulates the combined light beam in a manner consistent with stereoscopic image data to form first and second modulated images having substantially orthogonal polarization states. Projection optics project the modulated images onto a display surface.
