摘要
^3He原子磁强计利用^3He核自旋的拉莫尔进动测量磁场,具有高精度、小体积等特点,可以满足未来网络化磁异常探测对高性能磁强计的需求.围绕^3He原子磁强计的技术特点,重点介绍了该磁强计的基本工作原理及其硬件组成,分析了其理论灵敏度,给出了该磁强计的国内外研究情况,最后对该磁强计技术的未来发展进行了展望.
With the rapid progresses of frontier technologies such as quantum manipulation, atomic magnetometer based on ^3He nuclear, which features high precision, compact size, has becoming one of the main technologies of developing magnetic anomaly detection in the future. The basic operation principle and typical hardware structure of the atomic magnetometer based on ^3He are introduced firstly; the theoretical sensitivity is analyzed secondly; the recent progress of the atomic magnetometer based on ^3He are summarized thirdly; the development of the atomic magnetometer based on ^3He in the near future are prospected finally.
