CLOSED LOOP DRIVING OF A HIGHLIGHTER TYPE PROJECTOR

摘要

A method for driving a projection system and a projection system comprising a phase modulator and at least one amplitude modulator are described. The phase modulator is configured to generate a highlight image incident on the amplitude modulator, the projector system further comprises at least one image sensor configured to receive at least a portion of an illumination pattern substantially equivalent to the illumination pattern incident on the amplitude modulator, and the image sensor is being used to provide feedback to the controller of the projection system to improve the highlights projected by the projection system.
