FULL-FIELD PULSE-ECHO LASER ULTRASONIC PROPAGATION IMAGING DEVICE AND METHOD THEREOF

摘要

Provided are a full-field pulse-echo laser ultrasonic propagation imaging device and a method thereof. According to an embodiment of the present invention, a full-field ultrasonic propagation imaging system radiates a laser beam while scanning a structure to generate an ultrasonic wave in the structure and simultaneously senses an ultrasonic wave, propagated in a thickness direction, in the structure to generate a thickness direction ultrasonic propagation image. Therefore, damage information in a thickness direction can be visualized in the full-field of the structure through full-field pulse-echo laser ultrasonic propagation imaging.;COPYRIGHT KIPO 2016
