摘　　要：近年来,无自旋交换弛豫(Spin-Exchange Relaxation-Free,SERF)原子磁强计凭借其高灵敏度优势,在医学影像、低场磁共振和前沿物理研究等领域已开展广泛应用。传统的SERF原子磁强计多为单轴矢量测量,动态范围仅为nT量级。通过磁场调制等技术手段,可实现三轴磁场矢量测量,获得更丰富的磁场信息,进而通过施加三轴闭环控制,还可以大幅增加其动态范围,扩展SERF原子磁强计的应用领域,未来有望应用于空间磁探测中。综述了SERF原子磁强计的发展历程,重点阐述了三轴SERF原子磁强计近年来的国内外研究现状,对其发展方向进行了展望。In recent years,spin-exchange relaxation-free(SERF)atomic magnetometers have been widely used in medical imaging,low-field magnetic resonance,frontier physics research,and other fields by virtue of their high sensitivity.Conventional SERF atomic magnetometers are mostly single-axis vector sensors with dynamic ranges on the order of nT.Through magnetic field modulation and other technical means,three-axis magnetic field measurement can be achieved to obtain richer magnetic field information.Then,by applying three-axis closed-loop control,the dynamic range of the SERF atomic magnetometers can also be significantly increased,expanding its field of application,which is expected to be used in space magnetic exploration in the future.This paper provides an overview of the development process of the SERF atomic magnetometers,with a focus on the domestic and international research status of three-axis SERF atomic magnetometers in recent years,and gives an outlook on its development direction.
