Zhang, H., Wang, D. and Rahman, B. M. ORCID: 0000-0001-6384-0961 (2020). Parallel structured fiber in-line multiple Fabry-Perot cavities for high temperature sensing. Sensors and Actuators, A: Physical, 313, 112214.. doi: 10.1016/j.sna.2020.112214

Abstract

We propose and demonstrate a parallel structured fiber in-line interferometric device consisting of two sets of periodic internal mirrors which forms Fabry-Perot cavities with different cavity lengths. The output of the device contains two sets of overlapped fringe patterns, in which the main fringe peak is dominant and easy to identify. The cavity length of the internal mirror determines the spacing of the fringe peaks, which can be easily and flexibly controlled. The device is easy to operate or fabricated, simple in structure and exhibits high potential for high-temperature monitoring in harsh environments.
