A new method of non-contact generation and reception of surface wave is given. The mechanism of using pulsed laser to irradiate the surface of the specimen is theoretically analyzed. The Fabry-Perot interferometer interferometric system and its working principle are given. The ruby pulsed lasers are used to generate the surface wave and the confocal Fabry-Perot interferometer Ultrasonic detection system to receive surface waves to achieve a non-contact surface wave generation and recording, at the same time, the successful application of this technology for the surface of small open defects non-contact detection. The results show that this method is effective for the detection of surface defects.
