Abstract
In this paper, a cylindrical aluminum specimen with an eccentric circular hole is prepared and ultrasonic measurements are carried out by experimental means. The measurement area is restricted to the plane perpendicular to the axis of the cylindrical component. The measured wave data are fed into the approximate correction method formula—the Born inversion procedure—and cross-sectional images are obtained. Next, a 3D shape reconstruction of the defect in the aluminum specimen is performed by stacking the cross-sectional images. After correcting the defect’s echo amplitude, the defect reconstruction effect of the 2D section and 3D defect reconstruction effect improves remarkably.
