| Abstract: | LCoS light engine is an important component of the whole rear projection. The illumination system affects performance of LCoS rear projection remarkably. In this paper, each factor of affecting illumination effect is analyzed firstly, then an illumination system of LCoS light engine based on color LED light source is designed by ZEMAX software, which has only one chip, but has preferable luminance and uniformity and can meet the image requirement of the whole optical system. |
