摘要
原子磁力仪可分为标量磁力仪和矢量磁力仪两大类。标量磁力仪的测量结果与传感器的姿态无关,对平台的机动不敏感。矢量磁力仪能够获得更多的磁场信息,可以实现更精确的磁源定位。目前,共有7种三轴矢量原子磁力仪,测量方法分别为磁场扫描法、磁场旋转调制法、磁场轮流抵消法、磁场投影法、磁场交叉调制法、磁场分立调制法和自旋进动调制法。重点对上述7种三轴矢量原子磁力仪的测量方法进行了整理和分析。
There are two types of atomic magnetometer, the scalar atomic magnetometer and the vector atomic magnetometer. Scalar atomic magnetometer gives the same measurement output for different attitude so that it is insensitive to the movement of the platform. Vector atomic magnetometer can sense more magnetic information, thus can realize more precise localization of the magnetic sources. There are currently seven kinds of triaxial vector atomic magnetometers. The measurement methods are magnetic field scanning method, magnetic field rotation method, magnetic field compensation method,magnetic field projection method, magnetic field cross-modulation method, magnetic field separate modulation method and spin modulation method. In this paper, the above seven kinds of measurement methods of the three-axis vector atomic magnetometer are reviewed.
