Acoustic Holography (AH) equipment was used in a field environment to characterize defects in thick plate components. The program was successful and a large holographic data base was generated. Both optical and computer reconstruction techniques were used to produce AH images of selected defects. The report covers results on both production and non-production components, and describes the equipment and test configurations used to acquire the data. The portion of the program dealing with the production components includes comparative data for conventional NDE techniques (Radiographic and Ultrasonic), Acoustic Holography and destructive tests.
