Abstract
We propose a simple but compact hydrogen sensor based on Fabry-Perot (FP) type all fiber interferometer. The proposed sensor consists of two cascaded FP cavities formed with hollow core fiber (HOF) cavity, which is mainly used to compensate the influence of the unstable source power, and multi mode fiber (MMF) cavity coated with palladium as a sensing part. The experiment result shows that the exposed 4% hydrogen gas can be detected by the variation of interference fringe contrast with respect to optical property change of the palladium.
