Abstract
In this article, three dimensional Born inverse scattering method is modified to convenient form to reconstruct the shape of a three-dimensional flaw in an inhomogeneous cylindrical specimen. In this modified method, a measurement plane is restricted to the plane perpendicular to the axis of the inhomogeneous cylindrical specimen. Thus the cross-sectional image of the flaw can be obtained. By moving the measurement plane along the axis of the inhomogeneous cylindrical specimen, the cross-sectional image is obtained for each measurement plane. The three-dimensional flaw image is reconstructed by piling up the obtained cross-sectional images. Inhomogeneous cylindrical specimen with an eccentric circular cylindrical cavity model is prepared. The performance of the modified method to reconstruct the three-dimensional flaw is verified by using the experimentally measured waveforms. From the experimental research for the eccentric circular cylindrical defect, it is verified that the modified Born inversion works well for the volume type defect.
