Review of Progress in Quantitative Nondestructive Evaluation
Center for Nondestructive Evaluation

Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.

This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract

Ultrasonic measurements of materials are usually obtained from an electrical conversion of an acoustic signal by a transducer. ln this paper, a conventional (phase sensitive) transducer and a new phase insensitive acoustoelectric converter called an AEC are contrasted. In particular, the AEC is shown to exhibit superior characteristics for many typical experiments and appears to have many applications in the Nondestructive Evaluation (NOE) area.
