Optic fiber temperature sensor based on cascading fiber Bragg gratings
Source abstract
Abstract
In this paper, we demonstrate a novel method of distributed temperature sensing in optical fibers. The method is based on cascading fiber Bragg gratings (FBGs) single-ended Brillouin optical time-domain analyzer (BOTDA). This proposal applies the cascading FBGs both as a reflector and an optical filter to improves the measurement. Experimental results show that a 75-km sensing range with 3°C temperature resolution and 5 m spatial resolution are achieved.
