| 摘 要： | 光纤Bragg光栅(FBG)传感技术较其它光纤传感技术有其独特的优点，使其更具有研究的价值。基于光纤Bragg光栅的应变敏感性和磁性材料的磁致伸缩效应，提出了将光纤Bragg光栅应用于磁场传感测量的方案。设计方案中将光纤Bragg光栅与磁致伸缩材料相结合。实现了光纤Bragg光栅波长漂移量与侧向位移的线性调谐关系；通过测量光纤Bragg光栅波长漂移量，可以估算出外界磁场的强度变化。

| Abstract: | Compared with other fiber sensors, the fiber Bragg grating sensors have their unique merits,so they are more widely researched. Based on fiber Bragg grating susceptibility to stress and magnetostriction effect of magnetic materials, the scheme of using the fiber Bragg grating on detection for magnetic field is put forward in this paper. The scheme combines the fiber Bragg grating with magnetostrictive material, realizing the linear relationship of wavelength shift and vertical displacement. The density of magnetic field can be confirmed by measuring wavelength shift of fiber Bragg grating. |
