Eddy current tomography in cylindrical geometry

摘要

A tomographic approach is proposed for the inhomogeneities imaging in conductive media. We propose a linear discrete model for the resolution of the forward problem and a Bayesian probabilistic approach for the resolution of the inverse problem. Some results (simulated and real data) are presented to show the efficiency of the proposed method in spite of the modelization errors due to the Born approximation for linearizing the problem. Our specific application concerns the eddy current non-destructive evaluation of pipes.
