Abstract

Eddy-current imaging has been described in detail in previous publications [1,2,3]. As with other imaging systems, the image of an object represents blurring of the structures of the object by the system point spread function (PSF). Differing from other imaging systems, the PSF is very large and causes great spatial blurring of the object. This is because the eddy-current probe is a coil; its active area is much greater than the size of a beam of light, sound, or x-rays
