Abstract

To evaluate the out-of-plane displacement of surface acoustic wave, an air-coupled transducer is used to excite surface acoustic waves on an aluminium block, while another air-coupled transducer is adopted to record the leaky waves in association to the out-of-plane displacement. Measurements derived from the air-coupled ultrasonic method have good accordance as compared to the results attained by using a laser Doppler vibrometer. Considering the merits of low cost and safety, air-coupled ultrasonic method has good application prospects in future.
