光纤温度传感器高聚物传感介质的研究

Research of the Polymer sensitive medium for the Optical Fiber Temperature Sensor

根据光纤包层折射率随温度变化会引起传输光能损耗变化的原理，我们研制了油罐用光纤温度传感器。采用高聚物成膜工艺制作一种新型的光纤温度传感器探头。并对这种传感介质的作用进行了研究。

A optical fiber temperature sensor probe was prepared with polymer blends of polyvinyl and Florine-contained polymer materials It's behavior has been studied. polymer film have good transparency and could be controlled refractive index due to the decrease of molecular absorbability and polarizability.
