Temperature Characterization of Extrinsic Fiber Fabry-Perot Interferometric Sensor
The structure and fabrication method of the extrinsic fiber Fabry-Perot interference (EFPI) sensors are introduced. The influence of different cavity lengths and reflectivities on interference spectrum of the EFPI is analyzed through Matlab simulation, and a temperature sensing model of the EFPI sensor is established. Finally, temperature characteristics of the EFPI sensors with different cavity lengths and reflectivities are researched through a comparison experiment. The results indicate that the EFPI sensor with a short cavity fiber has a higher temperature sensitivity. In addition, the EFPI sensor coated with palladium-gold film can effectively avoid the influence of temperature on interference spectrum and compensate temperature fluctuation.
