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
In 1978, Murakami, et al. [1], applied the Wiener filter to the flaw characterization problem. The filter was used at that time and is still used as a means of desensitization to noise during deconvolution. In 1980, Elsley, et al. [2], outlined use of the Wiener filter as a maximum likelihood based scattering amplitude estimation technique. To date, the Wiener filter has not been applied explicitly in this manner. The intent of this paper is to explore use of the Wiener filter as a scattering amplitude estimation technique rather than as a means of desensitization.
