ABSTRACT:
An image display system includes a light source capable of generating an illumination light beam along an illumination path. The system also includes a modulator 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. The system further includes at least one adjustable illumination aperture operable to selectively control an amount of the at least a portion of the illumination light beam received by the modulator based at least in part on image data.
