Flaws characterization with pulsed eddy currents NDT [PDF]

open access: yesIEEE Transactions on Magnetics, 1999
In this paper, we present a method for characterizing flaws in metallic structures with pulsed eddy current nondestructive testing (NDT). In a first step, we explain why we have chosen a deconvolution method based on conjugate gradient algorithm (CG).
