利用红外场景仿真技术对红外成像系统进行测试已成为各国研究的热点。提出了一种基于数字微镜器件( DMD)的红外场景仿真系统设计方案, 对系统设计过程中各个组成部分进行了详细介绍, 并对系统的部分性能参数进行了分析, 如微镜片的衍射特性、能量转换效率、显示帧频等。最后, 结合系统的应用背景和存在的问题, 对下一步的研究工作做了展望。

It has become a research hotspot that infrared scene simulation is used to test the infrared imaging system. A design scheme of infrared scene simulation system based on DMD has been put forward, some major matters of the process of system design has been introduced in detail, and the optical performance of system has been analyzed, such as the diffraction characteristic of the DMD, the transfer efficiency of the system and the frame frequency of display. At last, with the background of application and the existent problems considered, next work has been planned.
