Video projector system

Some embodiments provide for a video projector system having a light engine, a video processing engine, and an optical engine. The light engine can provide narrow-band laser light to the optical engine module which modulates the laser light according to video signals received from the video processing engine. Some embodiments provide for a scanning system in the optical engine configured to scan light across one or more modulating elements from two or more colors. The light from two or more colors can be scanned across the modulating element such that the two or more colors are incident at different locations on the element at a particular time. Systems and methods for reducing speckle are presented in conjunction with the modular laser projector system.
