High-Resolution Flaw Detection Using Eddy Current Probe Array Based on Giant Magnetoresistance Sensors

This work presents a flaw detection system consisting of an array of eddy current (EC) probes based on giant-magnetoresistance (GMR) sensors for mapping the defects on a metal sheet. Before measurement, a spatially dependent calibration process was done to compensate for the interchannel inconsisten...
