摘要
对三种基于布里渊散射的高空间分辨率分布式光纤传感技术,即布里渊光纤时域分析暗光脉冲技术、布里渊光相关域分析及布里渊光频域分析技术,进行了详细阐述。分析了每种技术的工作原理,对每种技术所采用的实验系统配置、所能达到的空间分辨率进行了介绍,并对其存在的局限性进行了说明。
Three high spatial resolution distributed fiber sensing techniques, the dark-pulse technique of Brillouin optical time-domain analysis, the Brillouin optical correlation domain analysis and the Brillouin optical frequency domain analysis were expatiated in detail. The theory for each technique was analyzed, the experiment system configuration and the spatial resolution for each technique were introduced and the limitation for each technique was illuminated.
