OPTICAL SYSTEM WITH HIGH CONTRAST
摘要:
An optical system is disclosed that includes a housing that has an interior, a reflective interior surface, and a first opening. The optical system further includes a spatial light modulator that is disposed proximate the first opening and a light source that is disposed within the interior of the housing. The spatial light modulator modulates the light that is emitted by the light source to form image rays. The optical system further includes a first light redirecting film that is disposed proximate the first opening between the spatial light modulator and the light source. The first light redirecting film recycles at least a portion of the light that is emitted by the light source. The optical system further includes an optically absorptive film that is disposed proximate the first opening between the spatial light modulator and the viewing position. The optically absorptive film receives the image rays from the spatial light modulator and displays the received image rays to the viewing position.
