摘    要:阐述了一种基于布里渊放大结构的分布式光纤温度传感技术,该技术利用了光纤中布里渊频移与温度的依赖关系。本文从传感光纤的结构特点和材料的物性系数出发,在理论上证明了光纤温度与布里渊频移量之间存在线性关系。基于此传感技术建立了一实验系统。测试数据证明了理论分析的正确性。

关 键 词:分布式传感技术  光纤温度传感器  布里渊放大

Abstract:This paper describes the distributed optical fiber temperature sensing technique using Brillouin amplifier structure,which is based on the temperature induced changes in Brillouin frequency shift.The linear relationship between temperature and Brillouin frequency shift on sensing fiber is demonstrated theoredtically on the basis of the structure and material property of the sensing fiber.In addition,an expermental system is developed based on the sensing technique,some test data are obtained to confirm the theoretic analysis.
Keywords:distributed sensing technique  optical fiber temperature sensor  brillouin amplifier  brillouin frequency shift
