Here, the spatial distribution of fresnel diffraction field and different talbot effects of sinusoidal grating are presented, under three different illuminating conditions. especially, we discussed some interesting properties about fresnel diffraction field and talbot image, when sinusoidal grating is illuminated by divergent spherical wave
特別地，我們討論了發散球面波照明的情況下，菲涅耳衍射光場和泰伯像所具有的一些有趣的性質，如球面波對光場的放大作用，泰伯效應存在的條件等等。 -
Difference iterative method was used to estimate numerically director configurations in the nlc - bl037 cell in this paper. the refractive indices and phase retard of nlc in electric field was presented on the basis of the calculation of liquid crystal director distributions. then we analysed the diffraction phenomenon when the linearly polarized light was controlled by diffraction grating which was based on rectangular grating and sinusoidal phase grating models and we got it ’ s math model 。 finally we designed the nlc phase grating and we did the experiment to validate the theoretic calculation
文中利用差分迭代法計算了向列相液晶bl037盒中指向矢分佈的計算，根據指向矢的分佈情況得到了向列相液晶的雙折射率分佈和非常光通過液晶盒產生的相位延遲隨電壓變化;並在矩形光柵和正弦相位光柵的基礎上，分析了入射偏振光通過液晶電控光柵所產生的衍射情況。 -
In this thesis, we present the law and method to generate structured illumination based on fresnel diffraction. by applying rsd theory, we analyzed the spatial distribution of fresnel diffraction field of sinusoidal grating and its available application in 3d sensing
本文詳細地研究了基於菲涅耳衍射的結構照明的原理和方法，利用角譜理論（平面波衍射理論）分析了正弦光柵的衍射光場的空間分佈及其在三維傳感中應用的可能性。
