摘要
分析了基于法拉第效应的高精度光纤磁场传感器的理论基础和偏振结构 ,选择了灵敏度高、动态范围大的磁光晶体 ,并采用计算机模拟技术优化设计和评估性能 ,在 2GHz的频率范围内 。
The theoretical base and polarized optical configurations are analyzed. A magneto-optic crystal with high sensitivity and wide frequency response range is chosen, and computer simulation techniques are used to verify the optimum sensor design and components capability. Experiment results indicate good agreement between measurements and simulation at frequencies up to 2 GHz.
