Description

A multiviewing transducer, described in the companion paper in this volume (1) has been designed and developed to exploit advances in theoretical inverse elastic wave scattering in the long and intermediate wavelength regime. The multiviewing transducer concept is shown in Fig. 1. In addition, and as part of a broader effort to develop a decision tree for general flaw characterization shown in Fig. 2, a first generation set of post-processing data procedures has been developed and implemented for use with the multiprobe instrumentation. These procedures provide a 3-D reconstruction and characterization of volumetric flaws (size, shape, orientation and acoustic impedance estimates) and are shown by solid boxes in Fig. 2.
