| 摘 要： | 基于分光棱镜的光学耦合系统,设计了激光引信仿真系统.该系统通过将准直整形后的发射机窗口输出的激光束耦合进入校准夹具的光学系统中,通过光开关和程序控制的电控可变衰减器实时地模拟光束经过目标反射引起的光强衰减,最后将衰减后的光信号馈入激光引信的接收机窗口.该设计能够较为准确地模拟激光引信在交会过程中的回波光功率大小,并可实时地仿真激光引信各通道的回波信号,从而可以在实验室内验证激光引信信号处理系统的可靠性.

| Abstract: | A method of dispersion of light prism-based half kind simulation system was proposed for laser fuze.The lens optic coupling system were adopted to couple the light beam of sending window into the receiving window,Then real-time power attenuation simulation was realized by means of a Light switch and a Electric-controlled intensity attenuator.After being attenuated,the optical signals returned to windows of receiver.In the system,the optical coupling system is used to propagate laser pulses,so it can accurat... |
