基于布里渊后向散射的海水温度与盐度同步测量研究
Study on Simultaneous Measurement of Temperature and Salinity Based on Brillouin Scattering
摘要
基于布里渊散射信号的检测可实现对海水温度等参量的监测。由于海水的布里渊频移量是关于温度和盐度的二元函数,故无法仅通过布里渊散射频移量的检测实现对海水温度和盐度两个独立变量的精确测定。研究表明布里渊信号的功率也是关于温度和盐度的二元函数,所以文章提出通过测量布里渊频移量和接收布里渊信号功率大小,通过两个二元函数反演出海水的温度与盐度数值,实现对海水温度和盐度两个独立变量的同步测量。
Abstract
The parameters of seawater, such as temperature can be detected based on the detection of Brillouin scattering signal. Because Brillouin frequency shift is a function of two variables, temperature and salinity, the precise measurement about the two independent variables by Brillouin frequency shift is impossible. It is found power of Brillouin scattering signal is also a function of those two variables, so the method to simultaneously measure temperature and salinity by measuring the frequency shift and power is proposed and the synchronous measurement about temperature and salinity is realized.
