Considerable research has been directed toward applying hologram techniques to the recording of dynamic events. Single beam Fraunhofer holograms have been successfully used to study dynamic aerosols (Ref. 1-3). Two beam interferometer experiments have re-corded, shock waves, bullets and other moving objects, (Ref. 4, 5). This paper describes a hologram technique and instrument designed to record a large size range of moving objects over a deep sample volume. Several restrictions guided the approach taken. First, a Q-switched ruby laser was required to stop the object motion; this implies that coherence requirements be minimized. A simple optical system with as few elements as possible was desired so that the instrument could be readily engineered and operated. Photographic film, not plate, was required so that holograms could be recorded in rapid succession. Since film in general is of lower resolution than plate resolution, requirements on the film must be kept as low as possible. A large format was necessary to achieve a large sample volume; large objects as much as a centimeter in diameter at the near end of the volume and 100 m objects at the far end must be recorded simultaneously.
