摘要
为了提高弹丸速度测试的精度和抗干扰能力,提出了一种基于光电直流补偿的激光测速靶系统设计。采用了可靠性好,精度高的双启动、双停止区截激光幕速度测试方法,对抗强环境光干扰的光电直流补偿前置放大电路设计方案进行了分析。利用Microsoft VC++程序开发的速度测试软件进行了7.62mm弹丸单发速度测试实验,给出了实验波形。
In order to improve accuracy of projectile velocity measurement and anti-jamming capability, a system of laser screens for velocity measurement with photoelectric DC compensation was presented. The method of dual-startup, dualend, cut-off laser screens for velocity measurement was adopted. In addition, the photoelectric pre-amplifier circuit with DC compensation which is able to anti-jamming from strong ambient light was analyzed. The velocity measurement experiment of single 7.62mm projectile was conducted velocity measurement software based on Microsoft VC＋＋.
