摘要

长距离分布式光纤传感在管道安全、道路桥梁监测等领域都有迫切的需求。光啁啾链布里渊光时域分析被认为是快速分布式光纤传感的成功方案，本文提出了一种基于光啁啾链和布里渊损耗谱的超长传感范围的快速监测传感方案，在单模光纤上实现了3.2 s的测量时间、6 m的空间分辨率和150 km的传感范围。

Optical Chirp Chain BOTDA with 150 km sensing range based on Brillouin loss scheme

Long range distributed optical fiber sensing is urgently needed in many areas, such as pipeline safety, road and bridge monitoring, and so on. Optical chirp chain Brillouin optical time-domain analysis is considered successfully scheme of fast distributed optical fiber sensing, and here, we proposed a fast-monitoring sensing scheme with ultra-long sensing range, which is based on optical chirp chain and Brillouin loss spectrum, and a final parameter of 3.2-s measurement time, 6-m spatial resolution and 150-km sensing range have been achieved over a single-mode fiber.
