Abstract

The influence of coherence collapse due to Rayleigh backscattering on the scale of DFB fiber laser sensor array is investigated. The largest scales of a two-element sensor array and a three-element sensor array are measured to be 160 m and 250 m. Results indicate that coherence collapse due to Rayleigh backscattering does not limit the multiplexing capability of DFB fiber laser sensor array when the multiplexing capacity remains to be several tens, which is significant for the scale extension of DFB fiber laser sensor array.
