摘要

Abstract

For the measurement of vertical profiles of sound speed in the sea using laser excited Brillouin scattering

a high-resolution measurement of Brillouin frequency shift is required. In this work

a molecular absorption cell was selected as the frequency shift discrinator and several kinds of absorption gases were tried. It was found that the strong line (#1095) of127I2 at 18783.3297 cm−1 and two absorption lines of129I2 located at the two sides of the #1095 line of127I2 could be used as frequency shift discriminator to detect the changes of the Brillouin frequency shift. This selection is the best one within the range from 532.0131 nm to 532.5154 nm. But it is not perfect and there is a lot of work to do before its practical application.
