用于野外大口径火炮炮口弹丸姿态摄影的“激光高速摄影系统”

在大口径火炮发射瞬间,弹丸在炮口投飞行时,具有较高的飞行速度,并同时伴有强烈的炮口焰这就给弹丸炮口姿态的摄影带来困难。我们研制的“YDS激光高速摄影系统”可以排除强烈的炮口焰的干扰,拍摄下弹丸在炮口段飞行姿态的连续分幅照片,由于分幅是依靠调Q激光脉冲来分幅的,光脉冲宽度很窄,画幅曝光时间极短,故拍摄的高速飞行物体的照片相当清晰。 本文介绍了用于野外大口径火炮炮口弹丸姿态摄影的“YDS激光高速摄影系统”的组成,工作原理、组成摄影系统的各设备的作用,并扼要介绍了初步试验结果。

LASER HIGH-SPEED PHOTOGRAPHY SYSTEM USED TO TAKE PICTURES OF THE ATTITUDES OF FLYING PROJECTILE AT THE MUZZLE OF HEAVY CALIBRE GUN

Wher a heavy-calibre gun is fired and a projectile is flying near the gun muzzle, velocity of the projectile is very high and firing process is accompanying with strong muzzle flash. So taking the picture of the attitudes of flying projectile at the gun muzzle is very difficult"YDS Laser High-speed Photography System" developed by our group can take the framing pictures of the attitudes of the projectile and prevent them from flash confusing at the muzzle. Since framing depends on sequential pulse of the laset and the width of the pulse is very narrow, therefore the exposure time is - very short and photos of high-velocity flying body taken are very clear.This paper introduces configuration and operation principle of "YDS Laser High Speed Photo -graphy System" and the functions of the devices in this system. In addition, some experimental results are briefly introduced.
