| Abstract: | It is analyzed to achieve real time measurement of sound speed in sea water using Brillouin scattering.The relationship between Brillouin shift and sound speed are discussed theoretically.It is shown that the method with Brillouin scattering is good in real time,and it has very good accuracy in measurement.The experimental implementation and experimental result are given. |
