摘　　要：首次提出三次序列闪光正交阴影照相系统,在高分辨率CCD相机曝光时间内,脉冲激光器发出三次序列闪光,照明飞入视场的高速运动物体,得到运动物体三个位置处的阴影图像。这种阴影照相站实现了相当于传统三个阴影照相站的功能,且能解决小口径弹丸章动周期内布站间距过小的难题,将在现代靶道测量中获得广泛的应用。The fast shadow photograph system with three-sequence laser sparking is supposed for the first time.During the exposure time of the CCD camera,the pulsed laser sparks three times in sequence to emit ultra-short laser and three shadow images of the moving object at three different positions will be captured in one image frame.So one of this photograph station can achieve the function of three traditional photograph stations.And it can solve the problem of the space limitation for setting many stations in nutation periods of the small caliber projectile.This technology can be widely applied in modern ballistic range measurement.
