Abstract

The research focuses on measuring body wave by continuous laser scanning along the surface of aluminum plate. The model of aluminum plate was established by finite element method. The temperature near the upper edge rises, and the temperature rise is small. In infinite large aluminum plates, there are transverse and longitudinal wave front, and the wave front velocity is affected by the velocity of the scanning laser source. Finally, the wave front in plate bottom is used to identify the wave front type, which is generated by scanning laser and determined by combining the relationships between wave velocity and scanning velocity and Bscan diagram.
