Abstract
Described herein is a video projection system including an optical module with at least one collimated light source to generate a light beam and at least one movable mirror to reflect the light beam. The video projection system also includes a video source producing a digital video stream in accordance with a clock signal and a movement synchronization signal, as well as a projector system. The projector system includes mirror control circuitry configured to control movement of the at least one movable mirror in accordance with the clock signal and the movement synchronization signal, a light source controller configured to control generation of collimated light by the at least one collimated light source, and processing circuitry configured to receive the digital video stream, and to generate control signals for the light source controller based upon the received digital video stream.
