摘要
GJ 3 4 1小型遥控光电经纬仪在高速摄影机中采用了像增强器系统 ,提高光增益 ,亦即提高了暗、弱目标的信噪比。由于增强器系统具有复杂的、不容忽视的畸变效应 ,使得GJ 3 4 1小型遥控光电经纬仪在实现对暗、弱目标摄影记录的同时 ,也给测量测度带来了很大的影响。分析了造成这种影响的成因。用“网络板”法对像增强器系统的误差进行了实际测量 ,并讨论了如何消除其对GJ 3 4
An image intensifier system is used in a high speed camera of GJ 341 small remote control optical electronic theodolite It improves the optical gain or the signal to noise of the dark or weak targets To tract and measure dark or weak targets, it has a great effect in the measuring accuracy of the equipment for a high speed camera of GJ 341 small remote control optical electronic theodolite Not only the reason were analysed, which brings the effect, but also measured the distortion, and discussed how to relieve of the effect for a high speed camera of GJ 341 small remote control optical electronic theodolite
