Inverse problems of eddy current testing and uncertainties evaluation

Abstract

This paper deals with the problem of uncertainties evaluation when the procedure of inverse problems is used for processing the eddy current testing data. First the general inverse problem algorithm is described. Next the influence of different types of errors to the results of this algorithm is theoretically analyzed and some results are shown. These results show that the proper choice of the eddy current testing probe is important for achievement of accurate results of the inverse problem solution.
