INTFL - 8401 Computer Tomography for Interferomatic Aerodynamic Measurements.
Abstract
Under this research program the author has studied and developed several topics associated with the use of multidirectional holographic interferometry with data analysis by computer tomography for application to complex aerodynamic flows. In this technique, interferometer data are recorded virtually instantaneously by pulsed laser holographic interferometry and later are read out photometrically, digitized, and then processed by a computer to produce density maps in a set of planar cross sections of a three-dimensional flow. This program has included development of computer tomography codes of a new type, development of a microcomputer-controlled system for scanning interferograms and preprocessing the data, initial development of a new (non-holographic) hybrid optical/digital technique for recording information equivalent to that normally recorded on an interferogram of a flow, the execution of a simple prototype experiment, and considerable progress toward development of instrumentation for three-dimensional density measurement in a low-speed wind tunnel.
