空间光电探测器与地面距离较远 ,用脉冲或连续式激光直接损伤远场探测器非常困难。但光电探测器的光学接收系统对激光照射而言具有巨大的光学天线增益 ,实现激光对光电探测器的干扰与损伤是有可能的。通过计算 ,比较了脉冲激光与连续激光对远场光电探测器的作用效果 ,并在实验中验证了激光轴外干扰光电探测器系统的可行性 Space photodetectors are far away from the ground and it is very difficult to directly damage the far-field detectors with pulsed or continuous lasers. However, the photodetector optical receiving system has a huge optical antenna gain for laser irradiation, and it is possible to realize laser interference and damage to the photodetector. The effects of pulsed laser and continuous laser on the far-field photodetector are compared by calculation, and the feasibility of the laser off-axis photodetector system is verified in the experiment
