Parallel Dual-FPI Microcavity Hydrogen Sensor Based on the Vernier Effect

Year: 2026

Type: conference-paper

Abstract: A fiber-optic Fabry-Perot microcavity hydrogen sensor with a parallel dual-FPI structure and temperature compensation is developed. Over 0-5 percent hydrogen, it yields 7.718 nm per percent sensitivity, sub-48 s response, and 4.4-fold amplification. Spectral separation via FFT filtering and a sensitivity matrix suppress crosstalk, enabling simultaneous hydrogen-temperature measurement.
