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, the reported methods for solving the cross are introduced and analysed comparatively, and the development prospects are discussed.
