Ammunition flight attitude and warhead fragment power measurement are problems that need to be carefully considered in the process of weapon system trituration.The image measurement is very intuitive and credible.However, because of the influence of the flame, ordinary high speed photography is easy to achieve exposure saturation, that it cannot get the projectile's image in the flame.And for high speed moving projectile, ordinary high speed camera will also cause blur and trailing of the projectile's image.In this paper, it presents a multiple pulse laser test system, which can eliminate the interference of strong self-illumination, in order to get a clear image of high speed projectile.Through the test, this measurement system is effective and reliable, and it can better meet the demand of weapon system power transient test.
