Abstract
A light modulator configured to modulate at least two channels of an image to be projected and a lighting system configured to illuminate portions of the modulator corresponding to each channel with light having properties consistent with the channel. The channels comprise, for example, left and right channels of a 3D projection (e.g., a digital cinema projection). In one embodiment, the channels are provided by a multi-sectored filter wheel having at least one filter section for a first channel and at least one filter section for a second channel, where boundaries between the sectors are different in each section.
