Speckle mitigation in laser projection systems
Abstract:
Particular embodiments relate generally to laser projection systems and, more particularly, to systems and methods of reducing the appearance of speckle in laser projection images. According to one embodiment, a laser projection system comprising a light source and scanning optics is provided. The scanning optics include a plurality of frame generating optics configured to scan the output beam across a given projection surface to generate an image frame. The frame generating actuators are spatially separated such that output beams scanned by the frame generating actuators illuminate each common pixel portion of the image frames at a different incidence angle. The scanning optics also include an actuator selector positioned in an optical path of the output beam and configured to direct the output beam towards a selected one of the plurality of frame generating actuators.
