摘要

摘要: 为了满足二级轻气炮毫米级弹丸的测速需求，研制了一套利用激光光幕测量毫米级弹丸飞行速度的测试系统。采用光阑限光、光谱滤光和低阻滤波等复合抗干扰技术，解决了从强背景光中捕获快速变化的弱光扰动信号的技术问题，获得了较高的信噪比。在二级轻气炮上进行了直径为4 mm的球形金属弹丸测速实验，结果表明该装置的测量结果与线圈测速法实时监测结果的不一致性小于2%，可以满足毫米级弹丸速度测量的要求。

Abstract: A novel laser screen detection system was developed to measure the projectile's flight velocity in two-stage light gas-gun. By means of complex anti-jamming methods such as slit aperture limiting external stray light, narrow band spectrum filtering and low frequency notch filtering, the problem of detecting and catching the instantaneous weak disturbance signals from a bright background source was solved, and a high signal-noise ratio was achieved. A typical experiment of a spherical metal projectile with a diameter of 4 mm was performed in a two-stage light gas-gun. The results showed that the inconsistency in projectile's speed between this device and the coil for real-time monitoring is less than 2%, implying this device can meet the requirement of mm-size projectile's velocity measurement in two-stage light gas-gun.
