abstract = "Hydrogen explosions present a significant hazard to human life and related facilities. One effective way to reduce such accidents is to monitor multi-area leakages during the transmission and utilization of hydrogen. In this paper, we propose a quasi-distributed and high-sensitivity hydrogen sensor by the combination of the optical frequency domain reflectometry (OFDR) and multiple fiber-tip Fabry-Perot (FP) microcavities. The proposed sensor combines single-point and distributed optical fiber sensing, utilizing the detection mechanism of distributed sensing to demodulate the unit of single-point sensors. The total wavelength shift of reflection spectrum is approximately 4 nm as the hydrogen concentration increases from 0 to 4\%, and the response time is relatively short.",
