论文摘要

S. Seltzer和M. Romalis在2004年首先提出了基于Bloch方程的Bloch方程的准稳态解决方案的三轴矢量磁场测量方法,该方法于2004年提出,该磁场在2004年提出,该磁场引入了双轴零交叉磁场的模拟。调制频率必须足够缓慢,以使准稳态解决方案有效,否则测量精度将严重降低。因此,系统的带宽非常有限。为了增强根据调制频率限制的带宽,我们通过以时间依赖性方式求解Bloch方程来研究碱 - 原子自旋对高频调制场的响应。

The triaxial-vectorial magnetic field measurement method based on the quasi-steady-state solution of Bloch equation for SERF atomic magnetometry is firstly proposed by S. Seltzer and M. Romalis in 2004, which introduces dual-axis zero-crossing magnetic fields modulation. The modulation frequency must be slow enough that the quasi-steady-state solution is valid, otherwise the measurement accuracy will be seriously degraded. Thus the bandwidth of the system is greatly limited. In order to enhance the bandwidth constricted by the range of modulation frequency, we investigate the response of alkali-atomic spin to high-frequency modulation field by solving the Bloch equation in a time-dependence manner.
