【摘要】 分析了4光幕交汇测试弹丸着靶坐标的原理.4个光幕分别由4个大面积光幕靶产生.大面积光幕靶的光源采用发光二极管阵列,接收部分采用PIN红外光电二极管阵列,设计的大面积光幕靶发射部分与接收部分的有效作用距离最大可以达到3m.文中给出了详细的信号处理电路.设计的测试系统用5种轻武器枪弹实弹射击,测试结果与纸靶相比较,其测量误差满足目前枪弹产品检验试验的要求.更多还原

【Abstract】 A electro-optical measurement system for precise bullet location composed of four light screens with special geometrical frame is described respectively. Light source of the screens is formed by LED array. The PIN infrared photo-diodes array used as sensors. The longest effective distance between light source and sensors is 3 m. The detailed circuits of system are given. The measurement system was verified by using 5 kinds of small caliber pellets. As compared with the paper target sheet, the system designed can meet the demand of check-up test of gun, bullet and ammunition.更多还原
