基于超磁致伸缩效应的光纤电流传感器

Study of Optic Current Sensor Based on Giant Magnetostrictive Effect

基于超磁致伸缩效应的光纤电流传感器是目前研究的热点,在进行理论分析的基础上搭建了以光纤布拉格光栅和超磁致伸缩材料为传感头的电流传感系统,并将实验所得的结果与理论分析的结果进行了比较,得出了可能导致误差出现的原因.

Fiber optic current sensor based on giant magnetosWictive effect is the focus of current research. On the basis of theoretical analysis, a system based on Fiber Bragg Grating and giant magnetostrictive material current sensor system for sensing head is built, and a comparison between the experimental results and the theoretical analysis results is conducted and the possible causes of errors are identified.
