Abstract

Measurement of sound velocity in water by Brillouin scattering method was proposed in this paper. According to the relationship between Brillouin scattering and ocean parameters, the method for measuring sound velocity by stimulated Brillouin scattering frequency shift in water was analysed theoretically and experimentally. The theoretical calculation value of sound velocity in pure water and different salinity seawater were given. Based on this, the sound velocity in pure water and 35‰ salinity seawater has been measured experimentally. The results show that sound velocity in water is obtained accurately by using Brillouin scattering and the measured results are in good agreement with the theoretical results.
