查询词典 Fresnel integral

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。

By using holographic theory,hologram sampling theorem and separation condition of frequency spectrum,the maximum spatial frequency of off-axis Fresnel was analyzed,and recording conditions were studied.

根据全息理论，通过分析全息图光栅结构的极值频率，利用抽样定理以及频谱分离条件，分析了离轴菲涅耳全息的记录条件，得到了不同于以往文献的最小记录距离及参考光源设置表达式，并做了计算机模拟验证。

That is, movement adds only a fraction of the medium's velocity to the light (predicted by Fresnel in order to make Snell's law work in all frames of reference, consistent with stellar aberration).

即运动增添仅为介质的速度轻(预言菲涅尔为了使斯涅耳定律在各项工作的参照系，符合恒星像差)。

With the expression for the light propagation, the corresponding Snell's law and the expression of Fresnel coefficients are obtained, which can be applied to describe the re°ection-refraction event at the interface between an arbitrary combination of transparent and absorbing media.

并由此得到吸收介质界面上的反射和折射定律及其菲涅耳公式，所得结果也适用于由吸收和非吸收介质任意组合的界面。标签菲涅耳公式反射折射吸收折射率

Alternatively, the first stage may be another type of lens element, such as a Fresnel lens or a total internal reflection lens.

或者，第一级可能是另一类型的透镜元件，诸如菲涅耳透镜或全内反射透镜。

For single vug,when the lateral scale of vug is smaller than Fresnel radius,and the vertical scale is smaller than tuning thickness,the reflection amplitude of vug is proportional to its scale. For carbonate reservoir with random arranged vug,seismic wave amplitude is proportional to vug density.Key words random medium;forward modeling;carbonate;vug

对于单个的溶洞而言，当溶洞横向尺度小于菲涅尔带半径，纵向尺度小于调谐厚度时，溶洞反射振幅与溶洞尺度成正比例关系；对于随机分布孔洞的碳酸盐岩储层而言，地震波能量与孔洞密度成正比例关系。
