Development of Holographic Interferometric Applications in the VKF supersonic and Hypersonic Wind Tunnels

This report summarizes the progress achieved in the von Karman Gas Dynamics Facility (VKF) of the Arnold Engineering Development Center (AEDC), Air Force Systems Command (AFSC) to (1) improve the reconstruction process of holographic results, (2) develop diffuse, three-dimensional holography for use in the wind tunnel, and (3) prepare a data reduction program for converting interferometric results into meaningful static density distributions of a nonsymmetrical flow field. The report also contains some recommendations to make holography a more practical technique for recording optical results in the adverse environment existing around large supersonic and hypersonic wind tunnels.
