摘　　要：在考虑了超扭曲向列相液晶的双折射效应和超扭曲效应,探究了斜入射对超扭曲向列相液晶滤波器的输出特性的影响,并对其进行深入的理论分析和模拟,也推导出了其透射率的表达式。并且通过实验进一步验证了随着斜入射角的增大,超扭曲向列相液晶滤波器的透射峰值向短波方向移动,且其透射率与斜入射方向无关,与入射角有关。Considering the birefringence and super twisted effect of the super twisted nematic liquid crystal,the effect of oblique incidence on output characteristics of super twisted nematic liquid crystal filter was studied. The theory of super twisted nematic liquid crystal filter was analyzed,and the transmittance expression was derived according to optical theory. The further experiments verify that the transmittance is associated with incident angle,and has nothing to do with the direction of oblique incidence. With the increase of oblique incident angle,the transmittance peak of super twisted nematic liquid crystal filter shifts to short wavelength.
