红外动态目标模拟器光学系统的设计

设计了一种用于红外导引头性能测试的红外动态目标模拟器，利用数字微镜阵列(DMD)对黑体红外辐射进行反射调制，并由光学准直系统实现红外场景生成系统与红外导引头的光学耦合。用光学设计软件（ZEMAX）对准直光学系统进行了设计和优化，准直光学系统成像质量良好，接近衍射极限，点列图直径小于艾里斑直径，畸变小于0.1%。结果表明该系统环境适应性强，能很好地用于红外导引头动态图像的校准。

Design of Optical System for Infrared Dynamic Target Simulator

A type of dynamic infrared target simulator is designed for performance testing of infrared seeker. In the simulator, a Digital Micro mirror Device (DMD) is used to perform reflection modulation blackbody infrared radiation, and an optical collimation system is used to achieve optical coupling of infrared scene generation system and infrared seeker. Optical collimation system has been designed and optimized by using ZEMAX software, and good imaging quality was achieved by optical collimation system, which is close to diffraction limit, i.e., the diameter of spot diagram is smaller than that of the Airy and the distortion is less than 0.1%. Experimental results show that the system has very good environmental adaptability, can be used for calibration of infrared seeker very well.
