Abstract
This paper presents the characterization of a linear defect at several angles of rotation by a measurement system based on eddy current testing (ECT). The eddy current probe includes a planar coil and a giant magnetoresistor (GMR). The spatial eddy current distribution for each angle is obtained by an algorithm based in an image reconstruction technique solving the Biot-Savart inverse problem.
