A Search-Based Imaging System for Electromagnetic Nondestructive Testing
Winter 1989 (vol. 4 no. 4)
pp. 18-26

A crucial aspect of nondestructive-testing research is the inverse problem (or imaging), which involves the reconstruction of flaws in test specimen interiors, given a probe response signal. A novel approach that uses the finite-element model to solve the forward problem is presented. It is based on first formulating defect reconstruction as a parameter estimation problem. The test system functions as mathematical mapping from parameter space to signal space. The two major parts of the method are described: problem representation and the search procedure. Results obtained by applying the basic algorithm to defects simulated using the finite-element model are discussed.
