摘　　要：研究了由理想线偏振片和单轴双折射晶体波片组成的双折射滤光片倾斜放置时的二阶色散和三阶色散特性 ,包括波片厚度、光线入射角和光轴旋转角的变化对二阶和三阶色散的影响 .还给出了双折射滤光片的群延迟表达式 。We present theoretical investigations of the second and the third order group delay dispersion caused by a tilted birefringent filter (TBF). The expression for the group delay of TBF is deduced and the corresponding dispersions are calculated. The influence of the parameters such as the thickness, the tilting angle and the rotation angle of the birefringent plate on dispersions are discussed. Comparison between the dispersion characteristics of a Gires Tournois interferometer (GTI) and those of TBF is also present.
