| Abstract: | According to the characteristics of the laser and its special collimator, we designed a kind of laser projection display system with uniform illumination, using a light pipe as the light homogenization system. The light pipe has several advantages, such as a simple structure, a short period of development, and low cost. The simulation results show that luminous efficiency of the entire illumination system is 78%, and the uniformity is 85%, which reach the designed demands of the optical engine for the laser projection display system. |
