原子磁强计是利用原子在磁场中分裂出的塞曼能级间跃迁所构成的一种量子仪器。它们的测量精确度高于经典磁强计两个数量级以上。它们的测量范围上起25T,下至10~(-14)T,几乎覆盖了现今所能获得的磁场范围。本文综述利用各种极化方法获得原子塞曼能级的粒子数差,再根据不同观测能级跃迁的型式构成的十几种原子磁强计,适用于各种领域。
Atomic magnetometer is the use of atomic in the magnetic field split Zeeman class interstage transition posed by a quantum instrument. They measure more than two orders of magnitude more than classic magnetometers. They range from 25T down to 10 ~ (-14) T, covering almost the range of magnetic fields available today. In this paper, we review a dozen kinds of atomic magnetometers that use different polarization methods to obtain the atomic number of Zeeman level, and then use the different types of observational energy transitions for various fields.
