The influence of different cavity length and reflectivity on the interference spectrum of the extrinsic Fabry-Perot interference sensor was studied by Matlab simulation, and the temperature sensing model of extrinsic fiber Fabry-Perot interference sensor was established. Temperature contrast experiment on extrinsic fiber Fabry-Perot interferometer with different cavity length and different reflectivity. The results show that the temperature sensitivity of the extrinsic fiber Fabry-Perot interference sensor with short cavity is high, and the extrinsic fiber Fabry-Perot interference sensor with palladium film can avoid the influence of temperature on its interference spectrum The effect of temperature compensation.
