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 effects of sample thicknesses, frequencies, and values of lift-off on real and imaginary reluctances for a modified ac magnetic bridge were found for aluminum. Aluminum test samples with thicknesses varying between 0.406 and 6.35 millimeters were scanned at values of lift-off ranging from 0.1 to 0.38 millimeters and at frequencies between 200 and 5000 Hz.
