Laser Ultrasound for Nondestructive Testing.

Abstract

Noncontact techniques for generating and detecting high frequency ultrasonic waves (> 1 MHz) are being explored using pulsed laser thermoelastic transduction and heterodyne interferometry respectively. In addition holographic projection techniques are being investigated for beam shaping and beam steering of the thermoelastic waves. Possible applications of this technology include performance of ultrasonic nondestructive testing in hostile or inaccessible environments. (Author)
