We have developed a nondestructive surface-crack detection system by using laser ultrasound and optical 3D surface profilometry. The system can robustly acquire crack information by using the laser ultrasonic analysis data with visual surface profiling data where both data are produced by the same line-shaped pulse laser beam. By the help of the visual 3D shape data for a surface crack, this ultrasonic inspection system can provide reliable surface crack information. In this paper, the hardware configuration of the combined nondestructive laser inspection system to detect surface cracks will be described. Also, the experimental results to detect multi surface cracks by using the developed system will be presented.
