Use of holography for visualization of the wake of projectiles in hypersonic flight at March 6

Abstract

The essential requirement in visualizing the wake is to record the holograms of the phenomenon during a very short time, and the method described in this study uses a single-mode ruby laser as illuminating source. Also noted is the application of reflected diffuse light techniques to the recording of fast-moving objects in the case where the actual volume of the object space is more than 2 ft 3 (0.056 m 3).
