Abstract :
Summary form only given. Laser ultrasonics offers a technique for nondestructive, noncontact ultrasonic inspection. Progress has been made, which may enable this novel diagnostic to find its way into the manufacturing arena. We describe a novel technique, which may result in a compact, high-bandwidth low-cost laser based interferometric ultrasonic receiver.
