- Apparatus and method for full-field pulse-echo laser ultrasonic propagation imaging

摘要

A full-range pulse-echo laser ultrasound propagation imaging system and method are provided. The entire area ultrasonic wave propagation imaging system according to the present invention generates an ultrasonic wave in a structure by radiating a laser beam while scanning a structure and simultaneously senses ultrasonic waves propagating in a thickness direction in the structure to generate a thickness direction ultrasonic wave propagation image . This makes it possible to visualize damage information in the thickness direction in the entire region of the structure through the full-range pulse-echo laser ultrasonic wave propagation imaging.;
