菲涅耳衍射和夫琅禾费衍射 meaning in English

fresnel diffraction and fraunhofer diffraction

The topic we have tackled are as the following , ( 1 ) numerical simulation for light propagation and visualization of light - field distribution of fresnal diffraction and fraunhofer diffraction with ( 2 ) computation and display of hologram by method of simulation - anneal ( 3 ) hologram computation of a point source based on method of interference hologram computation
论文中具体完成了以下工作： 1 、对光的传播特性进行了数值模拟，以可视化方式表现了菲涅耳衍射和夫琅禾费衍射的光场分布。 2 、用模拟退火算法实现了全息图的计算及显示。 3 、在基于干涉全息图的计算方法上，计算了一个点光源的干涉全息图和相位分布。
The fresnel and franhufer diffraction patterns , of regular shapes screen such as slits , rectangular apertures , circle apertures , discs , triangle apertures , ronchi gratings , and some irregular shapes screen , are observed in the different propagation distance . this clearly gives the relation and difference of the two diffraction patterns
具体分析了规则形状如单缝、矩孔、圆孔、圆盘、三角孔、黑白光栅及一些不规则形状等孔径的菲涅耳衍射和夫琅禾费衍射图样强度分布，为深入理解菲涅耳衍射和夫琅禾费衍射及其内在联系与区别提供了理论依据。
