摘要
前向受激布里渊散射(F-SBS)是光纤中重要的三阶非线性效应,是进行外界物质识别和分析研究光纤物理特性的有力手段,成为近年研究的热点。本文通过对光纤中前向受激布里渊散射研究进展的调研和分析,整合了F-SBS的主要理论和传感原理,回顾了基于相位解调和能量转移探测的F-SBS测量手段,并重点介绍了本地光相位追溯技术、光力时域反射技术和光力时域分析技术等分布式传感技术。随着F-SBS传感器的逐渐实用化,对于F-SBS的高精度、高空间分辨力分布式测量的需求愈发显著,这将是未来光纤中前向受激布里渊散射的主要研究方向。
Forward stimulated Brillouin scattering(F-SBS),a 3-order nonlinear effect in optical fibers,has become the hotspot in recent years,due to its great potential in substance identification,and fiber diameter measurement,etc.Through research and analysis of the progress of F-SBS,the main principle and key techniques are generalized in this paper.Distributed sensing schemes based on local light phase recovery,opto-mechanical time-domain reflectometry,and opto-mechanical time-domain analysis are emphatically introduced here.With the gradual practical application of F-SBS,the demand for distributed measurement of F-SBS with high precision and high spatial resolution becomes more and more significant,which will be the main research direction of F-SBS in optical fibers in the future.
