The research on the fast photograph system with two sequence laser sparking

The fast photograph system with two sequence laser sparking source is supposed the first time.During the exposure time of the CCD camera,the laser source sparked twice in sequence to emit ultra-short pulsed laser and the two images of the moving object at two different positions is captured in one image frame so one photograph station achieved the function of the two photograph stations.This technology has great application values in modern ballistic measurement.
