Abstract
The new results of laser ballistic array photographic technique are presented in this paper. The characteristics of shadow, schlieren and front light photography with laser used in ballistic array system and their applied ranges are discussed. The techniques of automatic synchronous trigger by microcomputer are given. The automatic synchronous triggers can be finished in the case, as the velocity of the flying projectiles to be measured is not pre-known accurately and there is the large deviation of the velocity of the projectiles in flight according to the flying law of the projectile after launching. A new mathematical model is advanced and the microcomputer programs are designed. The experiment results show that the method is a success. The correcting technique of velocity attenuation rules of flying projectiles in air for the array photography system of several photographic stations to take more photos in long distance is described. Finally a few conclusions of the technique of laser high speed photography used in ballistic array are given.
