Abstract

A new method for analyzing the signal of the spectrum of Brillouin scattering in the ocean using F–P etalon and ICCD is proposed. It is based on the principle of interference of the F–P etalon. The capability of the method is confirmed by processing experimental data from stimulated Brillouin scattering spectrum in the water at different temperatures. The experimental results show very good agreement with theoretical values. This method provides a feasible way to measure Brillouin frequency shift and line width with high precision.
