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
Acoustic holography is an elegant and accurate technique for characterizing defects by forming visual images of them. Traditionally, optical reconstruction methods have been used to display the images but due to constraints of the optical systems, digital reconstruction techniques are now being employed.
