摘要
提出了一种新的基于前向布里渊散射(Forward Brillouin scattering,FBS)的 1060-XP 单模光纤(Single-mode fiber,SMF)温度和盐度判别传感方法.1060-XP 单模光纤中不同径向声学模式的测量频移具有对温度和盐度的不同敏感度.基于不同径向声学模式具有不同频移温度和频移盐度系数,本文提出了一种通过测量两个FBS散射峰的频移变化来同时测量温度和盐度的新方法.在概念验证实验中,温度和盐度的测量误差分别为0.12℃和0.29%.所提出的同时测量温度和盐度的方法在海洋测量、食品制造和制药工程等领域中具有潜在应用.
Abstract
A novel temperature and salinity discriminative sensing method based on forward Brillouin scattering(FBS)in 1060-XP single-mode fiber(SMF)is proposed.The measured frequency shifts corresponding to different radial acoustic modes in 1060-XP SMF show different sensitivities to temperature and salinity.Based on the new phenomenon that different radial acoustic modes have different frequency shift-temperature and frequency shift-salinity coefficients,we propose a novel method for simultaneously measuring temperature and salinity by measuring the frequency shift changes of two FBS scattering peaks.In a proof-of-concept experiment,the temperature and salinity measurement errors are 0.12℃and 0.29%,respectively.The proposed method for simultaneously measuring temperature and salinity has the potential applications such as ocean surveying,food manufacturing and pharmaceutical engineering.
