摘要
针对现有光纤传感器测量温度、磁场强度时灵敏度较低的问题, 提出了一种基于光信号的光纤温度磁场传感器。传感器以长周期光纤光栅(LPFG)级联光纤布喇格光栅(FBG)作为传感结构, 以磁流体作为磁性敏感材料, 采用HF溶液腐蚀光纤包层来提高灵敏度。首先介绍了传感器实现温度和磁场强度的双参量测量原理, 然后利用Optigrating仿真软件对LPFG-FBG传感单元进行模拟仿真, 最后根据仿真结果制作传感器并搭建实验环境进行温度和磁场强度的测量实验。实验结果表明: 当温度为35~85 ℃时, 传感器的温度灵敏度为85.7 pm/℃; 当磁场强度为4~20 mT时, 磁场强度灵敏度为65 pm/mT, 且稳定性良好。
Abstract
In view of the low sensitivity of existing optical fiber sensors in measuring temperature and magnetic field intensity, a optical fiber temperature and magnetic field sensor based on optical signal is proposed. The sensor designed has a long period fiber grating (LPFG) cascaded short period fiber Bragg grating (FBG) as the sensing structure. The magnetic fluid is used as magnetic sensitive material. The sensitivity is improved by using HF solution to etch the optical fiber cladding. Firstly, the principle of measuring temperature and magnetic field intensity by this sensor is introduced. Then, the LPFG-FBG sensor structure is simulated by using Optigating simulation software. Finally, the sensor is desinged and the experiments of measuring temperature and magnetic field intensity is conducted according to the simulation results. The experimental results show that the sensitivity of the sensor is 85.7 pm/℃ when the temperature is 35~85 ℃. When the magnetic field intensity ranges from 4~20 mT, the sensitivity of magnetic field intensity is 65 pm/mT, and the stability is good.
