Abstract: An imaging system (300) configured to reduce perceived flicker in three-dimensional images is provided. The imaging system (300) can include a plurality of light sources (305,306,307), a light combiner (302), a light modulator (303) and a polarization rotator (301). The light combiner (302) combines light received from each of the light sources into a combined beam (304). A first light portion (313) in the combined beam has a first light portion polarization state that is different from a second light portion polarization state of a second light portion (314). The light modulator (303) produces images by modulating the combined beam (304) along a projection surface (316). The polarization rotator (301) selectively rotates a polarization state of the combined beam (304) in synchrony with an image refresh cycle of the imaging system. A circular polarizer (1004) can be used to transform linear polarization states to circular polarization states.

Abstract: An imaging system (200) is configured to reduce perceived speckle (106) in images (201) by introducing angular diversity into consecutively projected images. The imaging system (200) includes one or more laser sources (203) that are configured to produce one or more light beams (215). A light modulator (204) scans these light beams (215) to produce images. A light translation element (206) introduces the angular diversity by physically altering a light reception location (208) on the light modulator (204) between refresh sweeps. To preserve image stability, image data (220) in a memory (218) can be correspondingly shifted.
