【摘要】 分布式光纤温度传感器釆用光纤拉曼散射效应测温,传感器所用的光纤既是传输介质又是传感介质是一种本征型的光纤传感器,它是—种光纤测温网络,也是一种光纤测温雷达系统。本文研究和讨论了分布式光纤拉曼放大器中背向瑞利散射和布里散射的放大效应,在放大器泵浦功率为800mw时,背向瑞利线的饱和增益达23dB,斯托克斯布里渊散射线的饱和增益达50dB,在此基础上,研究和讨论了光纤非线性散射效应的融合原理,研究和设计了一系列基于光纤非线性散射效应融合原理的新一代光纤传感器件,本文讨论了新一代的布里渊光时域分析器和集成分布式光纤拉曼放大器的超远程分布式光纤拉曼、布里渊散射光子传感器。更多还原

【Abstract】 Distributed optical fiber temperature sensor is based on Raman scattering temperature effect,the optical fiber is a transmission medium,is also sensing medium,it is a intrinsic type of optical fiber sensor,which is a kind of optical fiber temperature measurement network,is also a optical fiber temperature measurement radar system.The amplification effect of backward Rayleigh scattering and backward Brillouin scattering are studied in the FRA.The saturation gain of back Rayleigh scattering is 23dB and the saturation gain of back Brillouin scattering is 50dB in the FRA,during the pump power is 800mW.In the basis,the hybrid principle of fiber nonlinear effect is studied and a series generation of optical fiber sensors are studied and designed,based on the hybrid principle of fiber nonlinear effect.A generation of Brillouin optics domain analyzer and ultra long distance distributed optical fiber Raman and Brillouin scattering photons sensors are discussed in the paper.更多还原
