Abstract

A Fabry-Perot fiber-optic accelerometer based on the principle that the acceleration can be sensed through changing the length of the Fabry-Perot cavity by an inertial mass is designed and the Fizeau interferometer based demodulation principle and system for the designed Fabry-Perot fiber-optic accelerometer are proposed. Aiming at the Fizeau interferometer based demodulation principle and system for the designed Fabry-Perot fiber-optic accelerometer, the relative light intensity output from the Fizeau interferometer as a function of the length of the Fabry-Perot cavity and the wedge thickness of the Fizeau interferometer is established. In addition, the theoretical acceleration demodulation model for the Fabry-Perot fiber-optic accelerometer based on a Fizeau interferometer is also established. On these bases, the principle that the acceleration from the Fabry-Perot fiber-optic accelerometer can be demodulated based on the Fizeau interferometer is numerically simulated. The research results indicates the consistency of the simulated results with the theoretical analysis and the feasibility of the acceleration demodulation of the Fabry-Perot fiber-optic accelerometer based on the Fizeau interferometer.
