Background,Motivation and Objective In the manufacturing industrial structures with curved surfaces such as pipes, non-destructive testing during operation has been desired since defects and interior cracks could happen due to impact shock and vibration. Laser ultrasound visualization (LUV) system, which employs the pulsed laser to scan over the surface of monitoring area and an ultrasonic transducer to detect defects, could be an ideal solution since laser can generate all modes of ultrasound including guided waves so that it is suitable for fast scanning of large area.
