建立了描述原子蒸汽法拉第滤光器传输的完整理论。从物理角度解释了滤光片透射率与原子密度和外磁场强度的关系，以及透射率与频率的关系。作为例子，计算结果应用于正在进行的研究，以抑制天空背景，从而允许Na激光雷达在阳光条件下工作，并使测量中间层氧原子密度成为可能。(C) 2009年美国光学学会
A complete theory describing the transmission of atomic vapor Faraday filters is developed. The dependence of the filter transmission on atomic density and external magnetic field strength, as well as the frequency dependence of transmission, are explained in physical terms. As examples, applications of the computed results to ongoing research to suppress sky background, thus allowing Na lidar operation under sunlit conditions, and to enable measurement of the density of mesospheric oxygen atoms are briefly discussed.
