Abstract

The sequential pulsed, Q-switched ruby laser is used for the light source. Liodel 640 schilieren apparatus is used for the display optical system of image and flow field. The access type rotating mirror scanning high speed camera is used for recording unit. They are assembled into a complete set of Pulsed Laser High Speed Schlieren Photographic System. So far, we have designed and trial-manufactured two types. The Model I system is used for recording the armor-piercing process of the terminal trajectory and the chamber-shooting process of the midway trajectory. The better results have been obtained. The Eodel II system is used for studying the detonating mechanism of high energy dynamite. The framing pictures of the bullet flying attitude before bullet collides the target and the compressive deformation after it collides the target as well as the detonating process have been taken. These photos have provided the basis for research work. The future development of the system has also been discussed in this paper.
