A technique is described to reduce overfill of light that has exited a light integrating device and is applied to an optical modulator in the form of an illuminating pattern. The illumination reduction technique makes the illuminating pattern more closely conform to a active planar surface of the optical...http://www.google.ca/patents/US6964484?utm_source=gb-gplus-sharePatent US6964484 - Overfill reduction for an optical modulator
