磁流体包覆薄包层光纤光栅磁场传感研究
|
摘要
利用磁流体替代光纤布喇格光栅(FBG)的部分二氧化硅包层,制作了一种磁流体封装薄包层FBG结构的磁场传感器,研究了传感器对磁场和温度的响应特性。结果表明,在5.0～20.0mT的磁场范围内,传感器的波长灵敏度和功率灵敏度分别为34.9pm/mT和-1.063dBm/mT,波长线性响应度达到了99.2%。封装工艺未改变FBG波长随温度线性变化的特性,但受磁流体磁光效应影响,其温度灵敏度减小到9.2pm/℃。该传感器可实现磁场测量中的温度补偿,方法简单、易于实现。
By replacing part of silica cladding of fiber Bragg grating(FBG)with magnetic fluid,a magnetic field sensor with magnetic fluid packaging and thin cladding FBG structure has been fabricated.The response characteristics of the sensor to magnetic field and temperature have been investigated.The results show that the wavelength sensitivity and power sensitivity of the sensor are 34.9pm/mT and-1.063dBm/mT respectively in the magnetic field range of 5.0～20.0mT,and the corresponding linearity of the wavelength shifting with magnetic field change is up to 99.2%.The packaging process does not change the linearity of the FBG wavelength with temperature,but the temperature sensitivity is reduced to 9.2pm/°C due to the magneto-optical effect of the magnetic fluid.The sensor can realize temperature compensation in magnetic field measurement,and the method is simple and easy to implement.
