| 摘 要： | 在对薄膜材料热光效应和热膨胀特性研究的基础上,综合运用光学薄膜法布里-珀罗腔(Fabry-Perot)干涉理论,采用MATLAB 编程设计了纳米薄膜光纤法布里-珀罗传感器的仿真分析程序,模拟了薄膜型光纤法布里-珀罗传感探头反射光谱随温度变化的波长漂移特性,分析了不同材料热光效应和热膨胀特性对温度特性的影响权重,并进行了实验验证。验证结果表明,传感探头测试光谱的温度变化特性与仿真特性一致,纳米薄膜光纤法布里-珀罗传感器的理论仿真可用于选择纳米薄膜材料及筛选温度敏感且镀制容差大的膜系,对传感探头的研制具有指导意义。

| Abstract: | The temperature sensing principles of the nano-thin film fiber Fabry-Perot (F-P) sensor were analyzd. Based on the research of thermo-optic effect and thermal expansion property of the nano-thin film materials, MATLAB simulation program was designed to simulate the temperature characteristic of nano-thin film fiber F-P sensor based on F-P interference theory. The influence weights of thermo-optic effect and thermal expansion characteristics of different materials on temperature characteristics were analyzed. Experimental result shows that the temperature characteristic of interference fringes is almost the same as simulation. |
