Progresses of Simultaneous Sensing of Distributed Optical Fiber Temperature and Strain Based on Brillouin Scattering

摘要:

基于布里渊散射的光纤分布式传感技术可以实现对温度和应变的同时传感，如何解决温度、应变的交叉敏感问题是实现温度应变同时传感的关键。文章详细介绍了已报道的几种常见的实验方案，并对不同方案进行了比较分析，最后对未来的发展进行了展望。

Abstract:

Distributed optical fiber sensors based on Brillouin scattering can realize simultaneous temperature and strain sensing. But the cross sensitivity limits the practice of simultaneous sensing. In this paper, we introduce the present methods for solving the cross sensitivity that have been reported. We compare and analyse these different methods, finally discuss the development prospect.
