基于拉曼散射的分布式光纤测温主机设计与应用

摘要

This paper introduced a design scheme of the distributed fiber-optical temperature measurement mainframe which may be applied in the environment with slow temperature change. This scheme was based on the Raman scattering principle and used wavelength division multiplex ( WDM) , time division multiplex ( TDM) and space division multiplex ( SDM) for design, and it was suitable for the environment with slow temperature change. The test results showed that this distributed fiber-optical temperature measurement mainframe can accurately monitor the temperature and rapidly give early-warning.%介绍了一种适用于温度缓变场合的分布式光纤测温主机的设计方案，该方案基于拉曼散射原理，采用波分复用、时分复用和空分复用技术进行设计，适用于温度缓变环境。试验结果表明，采用该分布式光纤测温主机能够准确快速地对温度进行监测和预警。
