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。
In the exposure time of high-resolution CCD camera, the pulsed laser emits three sequential flashes to illuminate the high-speed moving objects flying into the field of view, and the shadow images of the moving objects at three positions are obtained. This shadow camera station realizes the function equivalent to that of the traditional three shadow camera stations and can solve the problem of too small distance between stations in the small-caliber projectile nutation cycle and will be widely used in modern track measurement.
