自然光入射时反射及折射光的偏振态与入射角之关系

Relation Between Polarized State of Reflected and Refracted Light and Angle of Incidence in Case of Unpolarized Light Incidence

应用菲涅耳公式对自然光入射时反射及折射光的偏振态与入射角之关系进行了讨论。发现对于反射光来说，在布儒斯特角两侧平行入射面的光振动与垂直入射面的光振动振幅之比不是一个对称关系；对于折射光来说，平行入射面的光振动与垂直入射面的光振动振幅之比是单调上升的。

In this paper,when incident light is unpolarized,the relation between the polarized states of the reflected and the refracted light and the angles of incidence is discussed in detail by Fresnel formula.It is found that the ratio between the amplitude of the light vibration parallel to the plane of incidence and the one normal to the plane of incidence in the reflected light is not symmetrical about Brewster angle.It is also found that the ratio between the two in the refracted light is monotone increasing.
