METHOD AND APPARATUS FOR MINIMIZATION OF SKEW LIGHT RAYS IN OPTICAL AND IMAGE PROJECTION SYSTEMS |
摘要 |
A method and apparatus for enhancing performance of a projection system by blocking incident angle light rays without increasing the F-number of the system includes a skew filter having a shaped aperture. The skew filter blocks a substantial portion of the skew light rays (36) while allowing other light rays (34) to pass through the projection system. The shape of the aperture relates to a constant contrast curve (50) of a polarizing beam splitter (24) for a cone of light incident on the polarizing beam splitter. ® KIPO & WIPO 2007
