Abstract:

A photographic system is described which uses two high-speed framing cameras, special illumination techniques, and appropriate synchronization to study the behavior of small underwater explosions in both the microsecond and millisecond time ranges. A Cordin camera is used to study pressure pulse behavior and the formation of cavitation fields. A Fastax camera is used to study the bubble effect and gross water motion. Typical results obtained from such a two-camera system are discussed in terms of one specific test.
