Abstract

A practicable method for liquid-surface acoustic-wave at the frequencies of a few tens Hertz, based on the combination of optical interference and scanning wave slope, has been developed. Moreover, this technique was used to determine the attenuation coefficient of the surface wave at these frequencies in real time.
