摘要
基于光电通讯领域中不断涌现出的高性能与带宽的光电仪器与器件,利用激光光束遮断原理,针对一级气体炮、二级轻气炮及火药炮等动高压加载手段,开展了内弹道弹速精密测量技术的实验研究,并研制一套紧凑型全光纤激光精密测量实验系统(简称:AFOBB-All fiber op-tical beam breakout)。通过百余发实验的工程应用,以及对实验数据的统计处理与分析表明,AFOBB系统完全满足精密物理实验的测试精度及可靠性要求,其速度测量的相对扩展不确定度小于0.8%,精确测量能力涵盖了几十m/s～7.0 km/s的弹速范围。
A set of all fiber optical beam breakout measurement system was designed and used in interior projectile velocity measurement.This system was based on the principle of optical beam breakout and advanced photoelectric technique.More than 100 shots were conducted on the one stage gas gun,two stage gas gun and powder gun.The result analysis showed that this projectile velocity measurement system could meet the accuracy and reliability requirements in precise physical experiments.The velocity measurement measurement extending uncertainty of this system is less than 0.8%.The velocity measurement range of this system is from tens of m/s to 7 km/s.
