Angle of Incidence The angle between an incident ray and the normal to a reflecting or refracting surface.

The ray corresponding to the wave surfaces tangent to the ellipsoids is deviated even though the incident ray is normal to the surface, and is called the extraordinary ray.

If the crystal is rotated about the incident ray as an axis, the ordinary ray remains fixed but the extraordinary ray revolves around it, as shown in Fig.

如果晶体绕入射线光轴转动，正常光线保持不动，而非常光线也绕它旋转，如图所显示的。

Find the relation between the incident ray and the final reflected ray.

The angle between the incident ray and a line perpendicular to the surface of the glass at the point where the incident ray strikes the glass is called the angle of incidence.

入射线和入射线打到玻璃上那点的玻璃面之垂直线间的角度被称为入射角。

When the reflected light returned from the original way and disturbed the incident ray, the reflectivity could not be tested easily and it was solved by using the method of double-ray testing.

结果表明，该镜头的猫眼效应绝对反射率最高可达35.87%，并且与焦距正比，与F数和入射角成反比；近场时的几何发散角与焦距和F数成反比。

Numerical simulations show that the results are accordant with conservation of energy; electrical field or magnetic field of the ray refracted to the isotropic medium does not parallel to the electric field or the magnetic field of original incident ray; the direction of optical axis and the magnitude of incident angle have a great effect on the energy and the polarization direction of the refracted ray.

数值模拟表明，所得结果满足能量守恒；射入各向同性介质中光的电场与原入射光的电场不再平行；光轴的取向和入射角的大小对折射光的偏振方向和能量有重大影响。

The incident ray、the refracted ray and the normal all lie in the same plane. The normal lies between the incident and refracted ray.

入射光线、折射光线和法线在同一平面内，且入射光线折射光线分居在法线两侧。

When the light ray refracts at the interface between a traditional positive-refractive-index material and a novel NIM, negative refraction occurs where the refracted ray and the incident ray lie on the same side of the normal line, which means that the emergence of NIMs changes the traditional propagating laws and the basic imaging properties of lenses.

当光波从传统的正折射率介质入射到负折射介质的界面时将发生折射光线与入射光线位于界面法线的同侧的负折射现象。

In order to meet the demand of precise measurement and applications, the principle of phase retardation with oblique incident angle is expounded, based on the total-reflection phase transformation theory of the phase retardation. By means of Fresnel rhomb, the variation law of the phase retardation for rhomb-type retarder with the incident angle is analyzed. The result indicates that incident angle has obvious influence over the phase retardation.The phase retardation is sensitive to the incident angle, and also has close correlation to incident position of the incident ray, which is asymmetrical to the incident position of the incident ray.

为满足精确应用和测量的需求，从相位延迟的全反射相变理论出发，阐述了斜入射相位延迟原理，以菲涅耳菱体为例，分析了菱体型相位延迟器相位延迟随其入射角变化的规律性，结果表明：当光线非严格准直时，光的入射角对相位延迟量有明显的影响，延迟量不但对入射角变化敏感，而且还与入射光线的入射方位密切相关，呈不对称形式。
