| Abstract: | This paper presents a novel distributed optical fiber sensor based on the microbend losses theory for monitoring the pipeline deformation, whose function is fulfilled by virtue of only one optical fiber with a self-pleached pattern and OTDR technique. Theory analysis and numerical simulate have shown the great application potential of this sensor. |
