Mixed Polarization Imaging System for Three-Dimensional Projection and Corresponding Methods |
摘要 |
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.
