摘要
基于光纤光栅的应变敏感性和磁性材料的磁致伸缩效应，本文探讨了将光纤均匀光栅应用于磁场传感测量的方案，计算了镍（Ｎｉ）和铽（Ｔｂ）两种强磁体条件下的磁致伸缩量ΔＬＬ、外磁场Ｈ、与Ｂｒａｇｇ波长位移量ΔλＢ和中心反射波长λ四个参数之间的相互关系，并进行了相关的讨论。
Based on fiber bragg grating susceptibility to stress and magnetostriction effect of magnetic materials,using the fiber bragg grating on detection scheme for magnetic field is discussed in this pepar,Each other relational curves of four parameters among magnetostriction ΔLL、outer maghetic field H、Bragg wavelength shift Δλ B together with reflected light central wavelength λ are given,under nickel and terbium both strong magnetical stuff conditions,and that is correlated with analyses,too.
