中文摘要：
Savart偏光镜是自行研制的新型稳态偏振干涉成像光谱仪中的核心部件，阐述了该Savart偏光镜的分光机理,基于电磁场边值条件，分析了入射面与Savart偏光镜左板主截面重合及垂直时，光透过Savart偏光镜各界面的反射和折射。得出了各界面透射系数的表达式以及Savart偏光镜透射率的理论计算公式．采用计算机模拟，给出了Savart偏光镜透射率随视场角和波长的变化曲线，并与研制的Savart偏光镜实验测试结果进行了分析比较，两者变化规律相符．表明该Savart偏光镜具有大视场、高通量的显著特点，适宜作为静态干涉仪和稳态偏振干涉成像光谱仪的高效横向剪切分束器，这为新型偏振干涉成像光谱技术的研究以及仪器研制提供了重要的理论依据．
英文摘要：
The Savart polariscope is the key spectroscopic component of the static polarization interference imaging spectrometer （SPIIS） that we have developed. The principle of beam splitting of Savart polariscope is described. This paper mainly studies the reflection and refraction of light incident from one medium to another when incident plane and the principle section of the left plate are coincident or perpendicular, according to electromagnetic boundary conditions. The transmission coefficient of each interface is deduced, and the total transmittance is given as a function of angle and wavelength of the incident light which is analyzed through computer simulation. It is proved in theory and by experiment that the Savart tolariseope has the advantages of both high flux and large field of view, and can be used as high performance lateral shearing beam splitter in static interferometer and SPIIS. This will provide the theoretical basis for the development of new polarization interference imaging spectral systems.
