AERONAUTICAL APPLICATIONS OF HOLOGRAPHIC INTERFEROMETRY.
Abstract
The advent of holography and the laser as an extremely intense, coherent light source has opened new dimensions in interferometric techniques. Precision optics are not required, alignment is not a critical factor, and three-dimensional interferograms of a flow field are obtainable. These are only a few of the advantages that stand out over present day interferometers. A brief outline of the holographic interferometric process and its capabilities is presented here. A detailed exposition of the continuous reconstruction beam technique is given from experience gained with such a device in the Department of Aeronautics of the Naval Postgraduate School. (Author)
