摘要 本文介绍了SERF(无自旋交换弛豫)态原子磁强计基本原理和检测方法,阐述了双光束交叉调制法和单光束分频调制法,这两种现有的地磁场下SERF态原子磁强计获得三轴磁场信息的检测方法.对两种方法在光路配置、零位偏置和灵敏度等方面的特性进行了比较,总结了双光束交叉调制法在y轴锁零控制方面存在的难度,得出了单光束分频调制的z轴方向灵敏度会随磁场减小而下降,同样导致锁零精度下降的结论. The basic theory and testing methods of SERF magnetometer are introduced. After describing two unshielded SERF magnetometer schemes, i.e. the dual-beam cross modulation scheme and the single - beam frequency division modulation scheme, the comparisons on optical path configuration, zero-bit offset and sensitivity are performed. Conclusively, the zero lock of dual-beam scheme in y axis is difficult and the sensitivity of single-beam scheme will decrease while the magnetic field decays, leading to the same problem that the zero lock precision declines.
