The Measuring System For The Bullet's Flying Time And Falling Velocity

A laser-applied velocity measuring and the bullet's flying time measuring device are put forward in this paper, which is to solve the shortage of the existing flying time and falling velocity tested system for the bullet, which is sharp declined in the sensibility and the precision and very difficult to catch the object. The laser communicating system and the laser range-measuring system is applied in this paper too, which can improve the measuring precision and the testing efficiency.In this paper, firstly, the laser target is demonstrated from many factors such as the chosen of the laser, the selection of the photoelectric receiver , Secondly, the advantage of the laser range-measuring system is clarified through the compare of several range-measuring manners and the anatomy of the laser range-measuring principle, then the measuring project for the bullet's flying time and the structure of the laser communicating system are introduced to prove the system satisfying with the measuring command.
