Abstract
A model is presented for the inversion of eddy-current data to be used for the detection of flaws. This model is based on rigorous electromagnetic theory and uses a multifrequency approach to make it truly three-dimensional. The resulting integral equations are discretized and solved using least squares techniques. The numerical problems involved in this algorithm are discussed, and a solution as well as examples of reconstructions of computer-generated flaws are presented.
