Description

It has proven possible to convert eddy current data associated with flaws to images of these flaws using holographic principles [2,3] because electromagnetic waves propagate in metals [1] and because these waves have subsonic velocities at eddy current frequencies. The purpose of this paper is to review and clarify the physical and mathematical basis for this method of analyzing eddy current data.
