Abstract

Using the specimens of two types with simulated surface defect and the specimen with actual crack, the detection of the surface defect and crack has been demonstrated by photoacoustic microscope. The surface defect of the first type is a group of mutually parallel two defects. The geometry of the second type is the defects crossing orthogonally each other. The specimen of third type is an actual crack. The PA images are obtained for the specimen with double and crossing defects. Furthermore, the detection of actual surface crack has been performed.
