Abstract
The laser ultrasonic method is highly applicable to in-process and in-line measurement as a technology that enables non-contact
ultrasonic detection. Previous studies have reported measurements using laser ultrasonic for various applications, however, most
were measurements using fixed systems. There is a need for a dynamic UT system in which the laser ultrasonic measurement system
itself can move. Therefore, we made it possible to mount the laser system on a robot arm by using a compact microchip laser as the
ultrasonic generation source. We measured the artificial back surface slit and verified its detectability performance as a dynamic
robot UT system.
