Abstract

this paper describes the experimental study of shockwave propagation conducted in high-speed real-time holographic interferometry and dual- reference-beam pulsed laser holographic interferometry. In these experiments, three kinds of holographic interferometers were used for visualizing and recording of the propagation of shockwave; a real-time holographic interferometer with high-speed framing camera, a real-time holographic interferometer with high-speed streak camera and a double pulsed ruby laser holographic interferometer with dual-reference-beam module. The holographic fringe patterns obtained from the first two interferometers could be used for qualitative analysis. However, the fringe patterns from the pulsed holographic interferometer could be processed digitally by phase stepping during reconstruction and the processed phase map demonstrated the possibility of quantitative analysis of high-speed flow phenomena.
