摘要

An image projection system (300, 400) uses a polarized illumination source (306) in conjunction with a linear polarizer (314) located before and a quarter-wave retarder (312) located after an imager field lens 118 along a projection optical axis (216) between a spatial light modulator reflective imager (120) and a projection lens (122). The combination serves to block illumination light (210a) reflected off the imager field lens (314) and other optics (408, 411), while passing illumination light (210c) modulated by ON-state reflector elements of the reflective imager 120. The reduction of ghost reflections and stray light improves dark state (OFF-state reflector element) contrast.
