摘要

In this paper, a novel light separator with contrast ratio enhancement but maintaining the optical efficiency of the DLP projection system is proposed. The main capability of the novel light separator is to direct the uncontrolled light away from the image system. The working theorem for the novel light separator is derived as well. Uncontrolled light is kept away from the image system by a total internal reflection surface, thereby effectively improving the image quality. Compared with previous work, the FO:FO contrast ratio can be improved from 46347:1 to 48250:1, the ANSI can be improved from 295:1 to 306:1, while the image system efficiency remains at 76.2%.
