Laser Photography of Hypervelocity Projectiles

Abstract
A photographic system is described which is capable of taking photographs of hypervelocity projectiles in a free‐flight range. The system consists of a Q‐switched laser, a simple lens camera, and related triggering circuitry. The film size is 73×95 mm which permits an image‐object ratio of two. Typical photographs of in‐flight projectiles traveling between 6.4 and 7.1 km/sec are presented.
