A pulsed ruby laser and specially constructed 'holocamera' were used to produce three dimensional, holographic images of explosively formed hypervelocity projectiles in flight. Velocities of the projectiles studied were up to 6500 m/s. Using this holographic technique it was possible to study interaction of these projectiles with solid targets and even the effects of detonation under water. The hologram proved particularly useful in the study of jets of low density materials which were transparent to X ray techniques.
