Computation of Eddy Current Signals and Quantitative Inversion with Realistic Probe Models

We have performed experiments to test both the physical correctness of the theory presented in an earlier paper (Muennemann et al., 1983), referred to below as MAFP, and the usefulness which it and its extension (Auld et al., 1984a) can achieve in practice. This paper describes the experiments performed and modifications to the earlier inversion procedure. These modifications were motivated by our “hands-on” experience applying the principles presented in the papers referred to above, particularly the extension to nonuniform fields.
