基于DMD的红外场景仿真系统光学引擎设计
Design of optical engine for infrared scene simulation system based on DMD
摘要
针对DMD(Digital Micromirror Device)器件是针对可见光波段设计,直接用于红外波段会遇到问题,提出了一种远心投影光学引擎架构,包括投影光学系统和照明光学系统.该光学引擎采用柯勒远心照明架构,并引入一片场镜来分离投影和照明光束.这种光学引擎结构紧凑、照明均匀、光能利用率高.
Abstract
DMD(Digital Micromirror Device) is originally designed for visible light spectrum, so it brings lots of problems when DMD is operated under infrared optics. To solve these problems, we provide a telecentric projection optical engine architecture, including projection optical system and illumination optical system. This optical engine employs Kohler telecentric illumination structure, and a field lens is introduced to separate the illumination beams and projection beams. This optical engine has good performance with compact structure, uniform lighting and high energy utilization efficiency.
