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。
The hysteresis loop of InBiCaVIG crystal is given, and the influence of hysteresis and magnetic saturation on the magneto-optical fiber sensor is analyzed in detail. When the measured magnetic field signal is alternating, the influence of hysteresis is mainly phase delay, which has little influence on amplitude and spectrum distribution. Saturation effect not only reduces the amplitude of response, but also leads to obvious spectrum change.
