分布式光纤温度传感器是近年来发展迅速的一种新型传感器.本文对此系统的基础——OTDR 技术及光纤中的散射与温度的依赖关系进行了分析研究,认为基于后向(?)曼散射的分布式光纤温度传感器很有生命力.
Distributed optical fiber temperature sensor is a new sensor developed rapidly in recent years.In this paper, the basis of this system - OTDR technology and optical fiber scattering and temperature-dependent relationship was analyzed and studied that based on backward (?) Man scattering Distributed fiber optic temperature sensor is very viable.
