摘　　要：设计了一种用于管道形变监测的光纤微弯传感器。它仅用一根多模光纤通过自编织形成微弯,完成对形变的传感功能。理论分析和数值模拟表明,该传感器在小应变范围内具有较好的线性响应,能有效监测管道形变,具有较大的应用价值。A novel optical fiber sensor based on the microbend losses theory for monitoring pipeline deformation is presented, whose function is fulfilled by virtue of only one optical fiber with a self-pleached pattern. Theory analysis and numerical simulation results show that this sensor has the great application potential.
