摘要：
In this paper the preliminary research results of distributed optical fiber vibration detection system based on Phi-OTDR are introduced This technology has a fine positioning accuracy of less than 20 m and multi-point positioning capability for the vibration signal within a 4 km sensing fiber. The dynamic frequency range has been currently validated between 1 Hz and 60 Hz. These results provide the reference for the vibration detection in the mechanical fault diagnosis.
