摘　　要：报道了一种计算法拉第反常色散滤光器（ＦＡＤＯＦ）透射谱的普遍方法。该方法可计算不同碱金属元素工作在任意电偶极跃迁和任意磁场强度下的法拉第反常色散滤光器透射谱，对主动式和被动式法拉第反常色散滤光器同样适用。该方法还可进一步推广到其它类型的原子滤光器（如斯塔克型原子滤光器）的计算。给出了采用这种方法对铷主动式７７５．９ｎｍ法拉第反常色散滤光器透射谱的计算结果，与实验曲线符合较好。A general calculation method to obtain the transmission spectrum of Faraday anomalous dispersion optical filter (FADOF) is presented. The theoretical scheme can be applied to any electrical dipole transmission of various atomic vapors and is valid for arbitrary magnetic fields. Moreover, the method can be used to predict the performance of both the passive FADOF and excited state FADOF (ESFADOF). It can also be extended to calculate the transmission spectrum of other new type atomic optical filters (such as Stark type atomic optical filters). The theoretical transmission curve of Rb 775.9 nm ESFADOF obtained by the general method is given, which agrees well with the experimental result.
