摘要： Disclosed is a technology that corrects astigmatism introduced by crossing beam splitting/combining plates. This technology may be used in the context of video projection systems, whereby the plates may be used for combining and/or splitting beams between two or more light modulating panels. In one embodiment, a system is provided for projecting an optical image, where the system includes a lens configured to receive and focus light rays to project the image. The system also includes a first beam splitting/combining plate that refracts light rays passing therethrough, where the refracting creates pluralities of light rays having corresponding optical paths causing each of the pluralities to be focused on corresponding focal planes by the lens. In addition, the system also includes a second beam splitting/combining plate configured to receive the pluralities of rays from the first beam splitting/combining plate, where the second beam splitting/combining plate is oriented with respect to the first beam splitting/combining plate so as to compensate the corresponding optical paths of the pluralities of rays such that each of the pluralities are focused on substantially the same focal plane by the lens.

摘要： This invention provides achromatic compound retarders, achromatic polarization switches, and achromatic shutters using the liquid crystal compound retarders. It further provides achromatic variable retardance smectic and nematic liquid crystal retarders. The achromatic compound retarders according to the invention are used to create achromatic inverters for display applications. The display comprises one or more retarders having in-plane retardance and in-plane orientation, at least one of the retarders being an actively controlled liquid crystal retarder, and a ferroelectric liquid crystal display, wherein the one or more retarders work in combination with the ferroelectric liquid crystal display to provide four states of brightness.
