Patent attributes
Particular embodiments relate generally to systems and methods of reducing the appearance of speckle in laser projection images. According to one embodiment, a laser projection system includes a light source, scanning optics and spinning optics. The light source includes at least one laser configured to emit an output beam. The scanning optics is positioned in an optical path of the output beam and configured to scan the output beam across a plurality of image pixels onto the spinning optics. The spinning optics is configured to create a virtual image of the scanning optics, translate the virtual image and change the angle of incidence of the output beam. The laser projection system is programmed to generate at least a portion of a scanned laser image, execute the translation of the virtual image by moving the spinning optics, and compensate for a relative image shift resulting from the translated virtual image.
