An automated multiviewing ultrasonic apparatus and signal processing routine have been developed for utilization in nondestructive evaluation (NDE) of materials. The instrument has been developed to take advantage of recent advances in long and intermediate wavelength inverse scattering of elastic waves, and provides a 3-D reconstruction of a flaw. Although the reconstruction obtained does not contain fine details of the flaw's structure, it provides sufficient information about the flaw (size, orientation, and selected materials properties) so that failure-predictive decisions can be made.
