摘要
较深入地分析了现已提出的分布式光纤传感器(DOFS)方案所存在的优、缺点。着重研究了如何实现高空间分辨率DOFS。并对利用孤子效应来提高喇曼散射DOFS的空间分辨率进行了分析。最后指出应考虑的两个方案。
In this texts,we review the various methods of Ditributed Optical Fiber Sensors(DOFS) that have been developed by now.The advantages and defaults of these methods to realize high spatial resolution DOFS are analyzed in detail. In the analysis,we also study the method of using soliton to get high spatial resolution in DOFS based on Raman scattering. In the end,Through the analysis we gain the two possible schemes to achieve high spatial resolution.
