Abstract

In this paper the inversion process is related to the eddy current evaluation of aluminum plates. A special probe that applies a spatially uniform excitation field is used. The excitation field is invariant under the probe translations and permits to simplify the resolution of the inverse problem. The inversion process consists on the approximate determination of the current density on the plate that permits the characterization of the defects geometry. The inversion is regularized by the Tikhonov method and the optimum regularization parameter is determined using the L-curve.
