| 摘 要： | 从亚稳态氦原子的Liouville方程和Bloch方程出发,研究了基于Mx构型的亚稳态氦原子的光磁双共振过程,建立了光探测磁共振线型的理论模型,并通过实验对幅值信号与相位信号的磁共振线型仿真结果进行验证，实测曲线与理论预测匹配较好。对共振线宽进行了估算,讨论了影响磁力仪工作灵敏度的磁力仪设计参数,这对Mx构型氦光泵磁力仪的研制有重要的指导意义。

| Abstract: | A theoretical model of the Mx-type optical-magnetic double resonance process of metastable Helium ensemble is analyzed. The theoretical expressions for the optical detection magnetic resonance pattern are derived and a dedicated experiment to measure the R-signal and the phase signal is performed. The results, from which the resonance linewidth is estimated, match the theoretical formula quite well. The factors affecting the sensitivity of the magnetometer are discussed, giving a guiding for designing Mx-type Helium magnetometer. |
