针对警用刑事实验室对自制枪发射的弹丸速度测试需求，设计了一种区截光幕传感器测量系统．该系统以光幕靶或天幕靶作为区截光幕，配接数据采集卡和处理软件构建了完整的测速系统．针对获取的弹丸波形数据，经过软件处理得到弹丸穿靶速度，从而判定枪弹的杀伤力．实弹射击试验表明，该系统可以准确可靠地测量直径最小为碬2 mm破片的速度，测试相对误差不超过0．1％，能够满足警用刑事实验室枪弹杀伤效果的检验要求．

According to the measurement requirement of the police penal lab ,a system of projectile velocity measurement is designed .T he system is mainly made up of light-screen sensors ,computer ,data acquisition card and analyzing and processing software .The zone-cut screens are often the light screens or sky screens .The projectile velocity is gotten after the bullet signals are analyzed and processed .Then the projectile lethality can be judged . T he ball firing has proved that the system can measure the traveling velocity of the projectile exactly and reliably ,and the test requirement of the gun or projectile’ s wreck can be satisfied in the police penal .The minimum diameter of the fragment is ?2 mm ,and the comparative error is under 0 .1% .
