Adaptive Illumination Modulator

摘要

An image display system (10) includes a light source (12) capable of generating an illumination light beam along an illumination path (32). The system also includes a modulator (22) operable to receive at least a portion of the illumination light beam and to selectively communicate at least some of the illumination light beam received by the modulator along a projection light path (34). The system further includes at least one adjustable illumination aperture (26) operable to selectively control an amount of the at least a portion of the illumination light beam received by the modulator (22) based at least in part on image data (38).
