摘要

目的　研究一套激光启动靶

以启动相应的设备或仪器开始工作

实现对弹丸运动的研究 .方法半导体激光光源经准直、扩束形成激光光幕

再经距光幕一定距离 (3～ 5 m )外的具有原向反射特性的微珠玻璃屏反射回来后

经球面反射镜的会聚由光电探测器接收 .结果　设计了一种大靶区面积、低噪声的光电探测系统及相应电路 .结论　当弹丸穿过光幕时

光电探测系统可获取弹丸过靶信号

Abstract

Aim\ To trigger others pertinent equipment and study the moving projectile across the laser screen

a new type laser screen has been developed. Methods\ By selecting semiconductor laser as light source and optical beam expander

a large area laser screen is formed toward a separated Scotchlite retroreflector at a distance some meters from the light source. The reflected light is collected by a spherical mirror on surface of a photodiode. Results\ A large area

low noise photo detectors and the corresponding circuit are designed. Conclusion\ This system can capture the signal as the projectile flies across the laser screen.
