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.
