Slope-assisted Raman distributed optical fiber sensing
文献摘要：
Raman distributed optical fiber sensing is required to achieve accurate temperature measurements in a micro-scale area.In this study,we first analyze and demonstrate the pulse transmission feature in the temperature variation area and the superposition characteristics of Raman optical time-domain reflectometry(OTDR)signals by numerical simulation.The equations of superimposed Raman anti-Stokes scattered signals at different stages are presented,providing a theoretical basis for the positioning and physical quantity demodulation of whole optical fiber systems based on the OTDR principle.Moreover,we propose and experimentally demonstrate a slope-assisted sensing principle and scheme in a Raman distributed optical fiber system.To the best our knowl-edge,this is the first experimental demonstration of Raman distributed optical fiber sensing in a centimeter-level spatial measurement region.
