【Abstract】 To measure the moving posture of the projectile in an all-weather shooting range for conventional weapon, an improved high speed streak camera system was developed by the usage of laser illumination and dual-lens photographic technique. The structure, technical parameter and fundamental function of the system has been briefty explained. The measurement of bullet velocity is described in detail. The velocity data are presented, and the uncertainty of the measurement is analyzed.更多还原
