Abstract
In this article, three-dimensional Kirchhoff inverse scattering method is modified to convenient form for a cylindrical specimen that includes three-dimensional defects including two-circle voids. Ultrasonic measurements are carried out. The measurement area in the modified methods is restricted in the plane perpendicular to the axis of cylindrical specimen. That's to say that the method is modified to convenient form to use measured waveforms in the x <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> -x <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> plane. The measured wave data are fed into the inversion method and cross-sectional images are obtained. We get the numerical results from all directions by finite element method. It is verified that the Kirchhoff inversion works well for shape reconstruction of defects.
