摘要
光源通过自准直平行光管发出平行光,此光束照射到安装在稳瞄转台前面的反射镜上,通过自准直平行光管后,形成汇聚光斑照射在检测器件PSD上,此时,控制摇摆台开始工作,稳瞄系统会克服由摇摆台产生的扰动,实现跟踪,通过后续处理电路和计算,可以测量机载光电稳瞄系统的稳定精度。
The light source emits parallel light through a self collimation parallel light tube,the beam is irradiated to the reflector mounted on the front of the stabilized platform,after self collimation collimator,forming a converging spot on the detection device PSD,control shaking table to start work, the stabilizing system can overcome the disturbance caused by the shaking table,by subsequent processing circuit and calculation,stability accuracy of airborne electro-optical stabilized sight system can be measured.
