Computerized ultrasonic data acquisition and signal analysis system

Ultrasonic analysis has proven to be a powerful nondestructive evaluation technique. Much of ultrasonics versatility is due to computerization. Computer signal processing and analysis allows the vast quantities of reflector information contained in an ultrasonic echo to be extracted and assimilated. A computerized, ultrasonic nondestructive evaluation facility has been developed at Sandia National Laboratories in Livermore. This report describes the facility and mentions a few of the studies being considered.
