长距离分布式光纤传感技术研究进展
Recent progress in ultra-long distributed fiber-optic sensing
摘要
Abstract
Distributed fiber-optic sensing (DFOS) is one of the most important parts in the fiber-optic sensing field,due to the following advantages:1) there is no need to manufacture sensors on the fiber;2) fibers are able to realize transmission and detection simultaneously;3) long-distance/large-scale sensing and networking can be accomplished prospectively;4) the spatial distribution and measurement information of physical parameters such as temperature,strain and vibration,can be obtained continuously along the fiber link,and the number of sensing points on a single fiber can be up to several tens of thousands.Due to the above tremendous superiority,DFOS has found wide application prospects,including perimeter security,oil/gas exploration,electrical facilities and structure monitoring,etc.This paper overviews recent progress in ultra-long distributed fiber-optic static (Brillouin optical time-domain analyzer) and dynamic (phase-sensitive optical time-domain reflectometer) sensing at Key Laboratory of Optical Fiber Sensing and Communications,UESTC.This paper summarizes our work on both basic and application studies.关键词
