| Abstract: | A fiber-optic Fabry-Perot (F-P) high-temperature sensor based on sapphire wafer was proposed and fabricated.The sensor uses the sapphire fiber with angled end face as a transmission waveguide,the sapphire wafer as a Fabry-Perot (F-P) interferometer and the structure of “Zirconia ferrule-Zirconia tube”as the fixing structure of the sensor.The reflection spectrum of the interferometer was demodulated by performing a combined algorithm of fast Fourier transform algorithm and minimum mean square error estimation.Temperature ranged from 20 ℃ to 1000 ℃ is measured,and the obtained precision is t2.5 ℃.The sensor has the advantages of small size,low cost,simple fabrication and high repeatability.It can be applied for stable and accurate temperature measurement in high temperature environments. |
