摘要
设计了一种分布式光纤管道形变传感器,它仅用一根光纤通过自缠绞形成微弯,完成对形变的传感功能。并采用OTDR技术实现分布式检测,对其传感机制建立了一新颖的理论模型。经理论分析和数值模拟表明,它可实时监测管道形变,具有很大的应用价值。
This paper presents a novel distributed optical fiber sensor for monitoring the pipeline deformation,whose function is fulfilled by only one optical fiber with a self-twisted pattern and OTDR technique.Theoretical research and data analysis based on original model about the response of mechanism have shown this sensor wsa effective to monitor the pipeline deformation.Value of application is great.
