High-temperature fiber-optic Fabry-Perot interferometric sensors
Review of Scientific Instruments
A photonic crystal fiber (PCF) based high-temperature fiber-optic sensor is proposed and experimentally demonstrated. The sensor head is a Fabry-Perot cavity manufactured with a short section of endless single-mode photonic crystal fiber (ESM PCF). The interferometric spectrum of the Fabry-Perot interferometer is collected by a charge coupled device linear array based micro spectrometer. A high-resolution demodulation algorithm is used to interrogate the peak wavelengths. Experimental resultsdoi:10.1063/1.4919409 pmid:26026548 fatcat:o6w74iwncfcodnmkwvpb6wwvpm
