Fiber optic quasi-distributed sensors for water leak detection

Crosstalk analysis of the in-line quasi-distributed low-coherence low-finesse Fabry–Pérot fiber-optic interferometric sensors

“…Quasi-distributed fiber-optic sensors have been extensively used in many applications such as distributed strain [1,2], temperature [3], and pH [4] measurements, water leak detection [5], optical path length variation [6], structural health monitoring [7], etc. A low-finesse intrinsic Fabry-Pérot interferometer can be employed as a typical sensing element, [8].…”
