摘　　要：在方棒照明系统的基础上,根据激光光源的发光特性和准直性,设计了一款用于激光投影显示的,基于光棒匀光的照明光路系统。此系统具有结构简单、开发周期短、加工成本低的优点。仿真结果表明：设计的激光投影机光能量利用率达到78%,均匀度达到85%,满足激光投影显示中对集光和照明的设计要求。
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.
