Paper Abstract

Since the early euphoria enveloping acoustical holography, considerable progress has been made in both application and technique. The major use for this imaging mode is in flaw characterization in thick structural materials such as used in the nuclear industry. Most recent advances derive from the development of piezoelectric arrays and microprocessors. The former allows data to be gathered at high speed and the latter allows the image to be reconstructed without the necessity of optics. In this paper, we describe some of these advances and offer experimental evidence for the optimism expressed by researchers in this field.
