摘　　要：具有特定视场的动态可见光目标模拟器是可见光成像系统测试与评估的关键设备,该模拟器的准直投影光学系统决定了基于数字微镜阵列(DMD)的动态景象投射器的性能。根据成像系统测试与评估需求,本文对可见光准直投影光学系统进行设计。基于对投影光学系统的参数计算,设计了视场58°的大视场可见光目标模拟器光学系统。将设计结果与成像光学系统进行匹配仿真,获得了良好的配合效果。通过对所研制的系统进行测试,实验结果表明所设计的光学系统完全满足模拟器的要求和对动态场景的仿真需求。Dynamic visible light target simulator with specific field is a key device for the testing and evaluation of the visible light imaging system, and the collimated projection optical system of this simulator determines the performance of the dynamic scene projector based on Digital Micromirror Device （DMD）. According to the imaging system test and evaluation requirements, the visible light collimated projector optical system is designed here. After the parameter calculation of optical projection system, a 58° large-field optical system of visible target simulator is designed according to the requirement of imaging system. The matched simulation is done between the design results with the imaging optical system, and the matched result is good. Experimental results show that the designed optical system meets the requirements of simulator and dynamic scene simulation completely.
