| 摘 要： | 给出了ＩｎＢｉＣａＶＩＧ晶体的磁滞回线，详细分析了磁滞及磁饱和效应对磁光光纤传感器的影响。当所测磁场信号为交变量时，磁滞的影响主要是相位延迟，对幅度及频谱分布影响较小；饱和效应不仅使响应幅值减小，同时还导致明显的频谱变化。

| Abstract: | In this paper, the magnetic hysteresis curves of In BiCaVIG crystal are given. The effects of magnetic hysteresis and saturation effects on a magneto optic fiber sensor is analyzed in detail. Magnetic hysteresis affects the phase delay mainly, and less the amplitude and frequency spectrum when the measured magnetic field signal is an alternating quantity. Magnetic saturation effects not only decrease the amplitude, but also change the frequency spectrum obviously. |
