摘要：
We describe a fiber optic extrinsic Fabry-Perot interferometer (EFPI) based temperature sensor that incorporates a pressure isolation fixture. The sensor has high temperature sensitivity and low pressure-induced crosstalk. The detailed analysis and discussion of the sensor design, the signal demodulation algorithm, and the sensor fabrication as well as the sensor performance are presented.
