Development and Application of a Laser Sheet Velocity Measurement System for Hypervelocity Small Projectile
|
Abstract:
In order to satisfy the demands of velocity measurement of hypervelocity small projectile in light gas-gun experiment,a novel laser sheet detection system was developed.In the system a series of technologies such as laser sheet compression,narrow band spectrum filtering,frequency notch filtering and broad band amplification were taken to solve the problem of low probability and liability to disturbance in velocity measurement of hypervelocity small projectile,and high signal-noise ratio was achieved.Typical...
