红外系统对入射激光的回射特性研究

Research on back reflected characteristics of incidence laser In IR system

介绍了红外系统的光学特性,从理论和实验上验证了激光辐照典型红外系统产生的回射激光。通过实验测 量了红外系统内光学元件产生回射激光的效率、光斑尺寸,分析了对回射激光光斑的识别。研究结果对充分利用回射激 光,开展激光对红外系统的主动跟踪、识别闭环具有一定的实际意义。

The optical character of IR system is introduced. The back reflectedlaser got when laser irradiated IR system is tested on the base of theory and experiment. Through experiment, the reflect efficiency of back - reflect laser from optical element in IR system, the laser spot and the identification ofback - reflected laser are measured. The research issuers have really signifi-cancefor the use of back - reflected laser, the illuminating tracking and identificationto IR system.
