摘要
提出了一种Solc型双折射滤波器的离轴消光比的一般性计算方法,利用所得结果模拟出了Solc型双折射滤波器的锥光干涉图以及发散光积分消光比与波长和发散角的关系曲线,实验结果证实了理论推算的合理性。 此外本方法也适用于计算各种类型双折射滤波器的离轴消光比。
Abstract
A generalized method is proposed for computing the off-axes extinction ratio of Solc birefringent filters. Based on the result, the conoscopic figures of Solc birefringent filters are simulated, and the curves of integral extinction versus wavelength and incident angular aperture are presented in the case of diffusive incidence. The calculated values agree well with the experimentally obtained values given here. Moreover, the method is suitable for computing the off-axes extinction ratio of all kinds of birefringent filters.
