摘要
介绍了非本征光纤法布里-珀罗干涉传感器的结构及制作方法。通过Matlab仿真研究不同腔长及反射率对非本征光纤法布里-珀罗干涉传感器干涉谱的影响,建立了非本征光纤法布里-珀罗干涉传感器的温度传感模型。对不同腔长及不同反射率的非本征光纤法布里-珀罗干涉传感器进行温度对比实验。结果表明,短腔的非本征光纤法布里-珀罗干涉传感器的温度灵敏度高;镀钯金膜的非本征光纤法布里-珀罗干涉传感器可较好地避免温度对其干涉谱的影响,具有温度补偿的作用。
Abstract
The structure and fabrication method of the extrinsic fiber Fabry-Perot interference (EFPI) sensors are introduced. The influence of different cavity lengths and reflectivities on interference spectrum of the EFPI is analyzed through Matlab simulation, and a temperature sensing model of the EFPI sensor is established. Finally, temperature characteristics of the EFPI sensors with different cavity lengths and reflectivities are researched through a comparison experiment. The results indicate that the EFPI sensor with a short cavity fiber has a higher temperature sensitivity. In addition, the EFPI sensor coated with palladium-gold film can effectively avoid the influence of temperature on interference spectrum and compensate temperature fluctuation.
