文中介绍了利用脉冲激光器的特性,实现一定时间间隔两次闪光照明弹丸,用普通照相机在同一底片上拍下两个弹丸影象,从底片上可求得弹丸飞行攻角及飞行速度。适用于30mm 口径以下的各种火炮弹丸,速度不受限制。文中详细介绍了原理以及设备的情况,并给出了实验结果及实物照片。 In this paper, the characteristics of pulsed laser are introduced to realize two flash illumination projectiles at a certain time interval. Two projectile images are captured on the same film with a normal camera. The projectile flight angle of attack and flight speed can be obtained from the film. Suitable for 30mm caliber of various artillery projectile, speed is not limited. The paper introduces the principle and the equipment in detail, and gives the experimental results and physical photos.
