新型原子滤光器-法拉第反常色散滤光器（FaradayAnomalousDisnersionOpticalFilter，FADOP）由置于正交们振场中的原子气室构成，它是利用在外部纵向磁场中原子能级的塞曼效应使谱线产生分裂，导致对线偏振入射光的左旋圆分量和右旋团分量的吸收和色散的不同而发生的旋光现象， The novel atomic filter Faraday Anomalous Dispersion Optical Filter (FADOP) consists of atomic gas chambers placed in the orthogonal vibronic field, which utilizes the Zeeman effect at the atomic level in the external longitudinal magnetic field to generate spectral lines Splitting, resulting in the phenomenon of rotation of the left-handed circularly polarized light component and the right-handed spin-on component of the absorption and dispersion of the incident light,
