Abstract

In this study, the nondestructive testing (NDT) of tilting surface defects has been demonstrated using a photoacoustic microscope (PAM). The tilting surface defects were fabricated on a metal plane specimen by mechanical processing. The obtained signal strength distribution was affected by the tilt angle of the surface defects, and it is possible to estimate the tilt angle of the surface defects from the gradient of the obtained signal strength distribution.
