针对目前分布式光纤传感器的优缺点，提出利用孤子效应的拉曼散射分布式光纤传感器系统构想。研究了高阶孤子对分布式光纤传感器的作用，对系统的性能参数进行分析，并在现有器件水平上分析了实现的可能性和存在的难点。 In view of the advantages and disadvantages of the current distributed optical fiber sensors, a Raman scattering distributed optical fiber sensor system using soliton effect is proposed. The effect of higher order solitons on distributed optical fiber sensors is studied, and the performance parameters of the system are analyzed. At the existing device level, the possibility of realization and the existing difficulties are analyzed.
