        激光显示照明光路中复眼透镜的设计

        发布时间:2018-07-07 00:05

        摘要

        设计激光投影机光学系统需要从如何减小光学系统的体积和提高激光光源的光效两个方面考虑。研究了激光显示照明系统中的复眼透镜, 并对设计的复眼小透镜矩形单元进行了优化, 发现在复眼透镜整体尺寸和单颗复眼小透镜焦距一定的情况下, 整个复眼透镜上的阵列越多, 即复眼透镜上蜂窝的数量越多, 其匀光效果就越好, 且此时投影机系统的体积也较小。为了提高激光光源的光效, 设计中对复眼透镜在不同数值孔径照明光束下的匀光效果进行了讨论。并对优化设计后的复眼透镜进行40 000条光线追迹, 实验显示其光线透过率可以达到92.5%, 且几乎无杂散光。

        Abstract

        It is an important research subject for the optical system of laser display on how to decrease the size of the optical system and improve the lighting effect of the laser source. The optical system design of the laser projector is mainly considered from these two aspects, and it can be found that when the size of the whole fly-eye lens and the focal length of the single fly-eye are certain, more arrays of the fly-eyewill be useful to increase the light effect and decrease the size of the optical engine. The lighting effect of the illumination beams with different numerical apertures and tracing 40 000 light lines of the optimized fly-eye lens show that the transmittance can reach about 92.5% with almost no stray light and scattered light.
