Quantitative detection of multi-frequency disturbance signal by φ-otdr system

HIGHLIGHTS

  • who: Manuscript version Accepted Manuscript and collaborators from the Hangkong University, China have published the paper: Quantitative detection of multi-frequency disturbance signal by u03c6-OTDR system, in the Journal: (JOURNAL)
  • how: This paper proposed to use the heterodyne coherent detection system with relatively simple structure to develop a new multi-frequency perturbation scheme and further verify it with the perturbation of the actual scene.

SUMMARY

    : Ac AUTHOR SUBMITTED MANUSCRIPT - MST-115568.R1 Nowadays, distributed optical fiber sensing (DOFS) gradually entered people`s field of vision. φ-OTDR exploits the self-coherence . . .
