摘要：

A novel Rayleigh noise suppression method is proposed to improve temperature accuracy and resolution for Raman distributed fiber-optics sensors. The proposed temperature demodulation method can eliminate temperature measurement inaccuracy caused by Rayleigh noise. The experimental results indicate that the temperature accuracy is optimized from 6.2 degrees C to 1.7 degrees C at a sensing distance of 9.1 km by using the proposed method, and the temperature resolution leads to about 1.5 degrees C improvement compared with the tradition demodulation method at a sensing distance of 10.0 km. The proposed method provides a robust and reliable high performance for long sensing ranges. (C) 2019 Optical Society of America
