Abstract:

This report documents work performed to improve the acoustical imaging capability of an acoustical holographic system for flaw detection. Included in the report is a mathematical model of the acoustical system and the results of the experimental effort to improve it. Added improvements include new plexiglas acoustical lenses, a lens gymbal mount, object gymbal mount, and acoustical thermoplastic memory. An attempt to use glycerine as a new acoustical couplant media is also reported. Work is also reported about the generation of acoustical real time speckle interferograms using the system.
