为了实现石英光滤波器中心波长随角度变化不敏感的目的，利用石英光滤波器绕着平行于或垂直于石英光轴的方向旋转时，石英光滤波器输出中心波长漂移方向不同的原理，提出了一个新型的两级改进型的Lyot石英光滤波器滤波的方法，并进行了相关理论分析和实验验证。结果表明，当入射角小于18°时，这个新型的光滤波器的中心输出波长的确对入射角度的变化不敏感。该结论与相关的实验结果是相符合的。

In order to achieve a quartz filter insensitive to incident angles , based on the principle that the shifting direction of output central wavelength of a quartz birefringent optical filter is different when the filter rotate around an axis parallel and perpendicular to the quartz optical axis , a new type of two-stage modified Lyot quartz filter was presented .After theoretical analysis and experimental verification , the results show that the central wavelength of this new type filter is actually insensitive to the incident angles less than 18°.The conclusion is in good agreement with the experiment results .
