摘要 设计了一种由两根光纤相互绞合形成微弯的管道形变传感器。对其传感机制建立了一新颖的理论模型,并通过理论研究和数值分析表明,它不仅能实时监测管道是否发生形变,而且当采用OTDR技术时还能确定形变的位置及程度,具有很大的应用价值。 This paper presents a novel optical fiber sensor with the pattern of twisting two fiber together. Theoretical research and numerical analysis based on a original model about the response mechanism have shown this sensor is effective to monitor the place and degree of the pipeline deformation by OTDR technique. It's application potential is great.
