Laser ultrasonic techniques (LUTs) perform an inspection based on raster scanning pattern to obtain three-dimensional (3D) ultrasonic signals for damage detection in mechanical structures. Even though the raster scan-based in LUTs provides full-field ultrasonic data with high spatial resolution, the scan process consumes substantial time and generates redundant ultrasonic data in many applications. In this paper, statistical damage detection based on the full-field covariance of circumferential… CONTINUE READING
