Improving a Real Time Acoustical Holographic System for Flaw Detection

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.
