摘　　要：里德堡(Rydberg)原子具有极大的极化率和电偶极矩,并对外电场十分敏感,因此可利用Rydberg原子的量子干涉效应实现微波和太赫兹场的高精确度、自校准测量,基于Rydberg原子对太赫兹波频率上转换效应可实现太赫兹波段的实时成像。本文回顾了利用Rydberg原子的电磁诱导透明效应和Autler-Townes分裂现象实现对微波和太赫兹场的高精确度探测的研究进展,以及Rydberg原子在快速太赫兹成像方面的研究。Rydberg atoms can be used for high-precision,self-calibrating measurements of microwave and terahertz fields due to their large polarizability and electric dipole moments and high sensitivity to external electric fields.In this paper,the research progress of using the Electromagnetically Induced Transparency(EIT)effect and the Autler-Townes(AT)splitting of Rydberg atoms to achieve high-precision detection of microwave and terahertz fields,is reviewed,as well as the research of Rydberg atoms in fast terahertz imaging.
