摘要
目前国内外报道了几种矢量原子磁力仪的技术方案,其中基于磁场旋转调制法的矢量原子磁力仪可实现对矢量磁场的连续测量。本文对磁场旋转调制法矢量原子磁力仪的工作原理进行了阐述,对“旋转磁场”的设计、产生以及标定方法进行了介绍,在此基础上基于抽运-检测型原子磁力仪对旋转磁场和矢量磁场的叠加磁场进行了实验测量,验证了实测磁场的平均值、峰峰值与理论计算结果的符合情况,分析了实测磁场的平均值与理论平均值的偏差起源,并通过实验验证了矢量原子磁力仪的连续测量能力。研究内容为连续测量型矢量原子磁力仪的研制奠定了技术基础。
At present, several technical schemes of vector atomic magnetometer have been reported at home and abroad, and a vector atomic magnetometer based on magnetic field rotation-modulation method can realize the continuous measurement of vector magnetic field. In this paper, the working principle of the vector atomic magnetometer based on the magnetic field rotation-modulation method is described, and the design, generation and calibration method of the "rotating magnetic field" are introduced. Then, the superposition magnetic field of the rotating magnetic field and the vector magnetic field is experimentally measured by a pump-probe atomic magnetometer. The coincidences of the average value and peak-to-peak value of the measured magnetic field with the theoretical calculation results are verified, and the origins of the deviation between the average values of the measured magnetic field and the theoretical results are analyzed. At last, the continuous measurement ability of vector atomic magnetometer is verified by experiments. The research content of this paper lays a technical foundation for the development of continuous measurement vector atomic magnetometer.
