摘　　要：为了解决传统光幕靶靶面小、灵敏度低、结构复杂等问题,分析了一种镜头式光幕靶的工作原理,搭建了相应的原理样机,设计了一种可监测镜头式光幕靶状态、具有程控放大功能的信号处理电路.经过气枪实弹测试验证,当电路设置为低灵敏度状态时,对于弹径为5mm、过幕点距离镜头1m处的弹丸,信号处理电路输出信号幅值达到2V以上,噪声信号控制在0.5V以内.In order to solve the problems of the traditional light screens of small target surface, low sensitivity and complex structure, the principle of the lens type light screen was analyzed, the corresponding prototype was built and the signal processing circuits were designed. The circuits can monitor the state of the lens type light screen and have the function of programmable amplify. By testing the circuits with bullets, it showed that the output signal amplitude of the signal processing circuit reached more than 2 V, the noise signal was controlled within 0. 5 V when the circuits were set to the low sensitivity state, the diameter of the bullet was 5mm and the point of impact was lm away from the lens.
