Multi-core fiber enabled fading noise suppression in ϕ-OFDR based quantitative distributed vibration sensing

Yuxiang Feng, Weilin Xie, Yinxia Meng +7

Coherent fading has been regarded as a critical issue in phase-sensitive optical frequency domain reflectometry (ϕ-OFDR) based distributed fiber-optic sensing. Here, we report on a…
