摘　　要： 介绍了自旋调制标量原子磁强计矢量化测试方法,从主磁场幅值和横向磁场的测试灵敏度得到该方法的磁场方向测量灵敏度为0.75μrad/Hz^(1/2)。从磁场方向测量的角度与其他标量原子磁强计矢量化测量方法进行了对比,表明:该方法更简洁,并且能直接给出主磁场方向与磁力线的偏离信号,在地震地磁监测和磁力线寻的制导等领域中具有独特的应用价值。 A measurement method of vectorization for spin modulated scalar magnetometer is introduced.Measurement sensitivity of the magnetic field direction in this way is 0. 75 μrad/Hz^（1/2）,with the results of the experiment in main magnetic field amplitude and the sensitivity of the transverse magnetic field. Compared with other measurement methods of vectorization for scalar magnetometer in the direction of magnetic field,this method is more concise. In addition,it can show the main magnetic field direction and the deviation signal of magnetic lines of force directly,which has an unique application value in geomagnetic monitoring of earthquake and homing guidance of magnetic lines of force and other field.
