Ultrasonic and Acoustic Holographic Techniques for Inspection of Composite Gun Tubes and Other Weapon Components.

摘要

Ultrasonic and acoustic holographic imaging has been shown to be an effective procedure for the nondestructive inspection of flaws and voids in composite and other material structures. Techniques for quantitatively imaging the size, shape and distribution of flaws in composites and conventional materials are dicussed. Additionally a number of test results representing applications of ultrasonic and holographic imaging and their adaptation to typical material testing problems are presented. (Author)
