摘要
从光纤光栅温度传感模型出发,分析研究光纤光栅的温度传感特性,比较裸光纤光栅与增敏光纤光栅的温度敏感性,在此基础上提出一种基于滤波法的光纤光栅解调系统,研究表明,此系统具有结构简单,操作方便,灵敏度高的优点。
From a temperature sensing model of fiber bragg grating, the paper analyses the property of fiber bragg grating temperature sensing is and compares the temperature sensitivity between bare fiber bragg grating and fiber bragg grating of aggrandizing sensitivity. A fiber bragg grating demodulation system is proposed based on filtration, The researches indicate that the system has advantages of simple configuration, easy operation and high sensitivity.
