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
The use of non-contact ultrasonic techniques for the inspection of wings, tail sections and fuselages of aircraft in the field environment is an attractive alternative to current contact or squirter approaches. This paper reports on the use of laser generation and detection of ultrasound for flaw detection in Gr/Epoxy composite panels. Laser-based ultrasonics is a well documented technique which has been demonstrated by many researchers [1–8] and is being applied in several industrial areas [9–11].
