Three-dimensional shock wave phenomena visualized with holographic interferometry

Double-exposed holographic interferograms of 3D shock wave phenomena are presented. Details of experiments and the equipment used are also briefly described. Advantages of this kind of visualization technique are pointed out with the examples of a normal shock generated in an air shock tube for a straight channel, T-junction and sudden enlargement channels, channels with differently shaped obstacles.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
