依据建立的可见光波长与MATLAB色谱矩阵参数的映射关系,把按照真实实验参数计算获得的杨氏干涉实验干涉图样的强度分布,变成了用于干涉图样显示的色谱矩阵,从而实现了单色光杨氏干涉实验的计算机写真;以同样的方式获得了单色光圆孔夫琅和费衍射实验的计算机写真。以此为铺垫,根据颜色匹配理论和计算机颜色显示的叠加原理,用波长分别为700 nm（红）、546.1 nm（绿）和435.8 nm（蓝）的光谱色为三原色匹配等能白光,实现白光杨氏干涉和圆孔夫琅和费衍射图样的计算机仿真。这种方法可广泛用于与可见光有关的色散、激光传播规律、空间滤波等物理现象讨论与分析。
依據建立的可見光波長與MATLAB色譜矩陣參數的映射關繫,把按照真實實驗參數計算穫得的楊氏榦涉實驗榦涉圖樣的彊度分佈,變成瞭用于榦涉圖樣顯示的色譜矩陣,從而實現瞭單色光楊氏榦涉實驗的計算機寫真;以同樣的方式穫得瞭單色光圓孔伕瑯和費衍射實驗的計算機寫真。以此為鋪墊,根據顏色匹配理論和計算機顏色顯示的疊加原理,用波長分彆為700 nm（紅）、546.1 nm（綠）和435.8 nm（藍）的光譜色為三原色匹配等能白光,實現白光楊氏榦涉和圓孔伕瑯和費衍射圖樣的計算機倣真。這種方法可廣汎用于與可見光有關的色散、激光傳播規律、空間濾波等物理現象討論與分析。

Based on mapping relationship between visible wavelength and data in colormap matrix of MATLAB which was erected in reference,the intensity distribution of interference patterns of Young′s experiment,calculated by inputting actual experimental data,turns to colormap matrix of interference pattern.As a result,describing interference pattern of monochromatic Young′s experiment as it is with computer is realized.So do as the former,the monochromatic Fraunhofer diffraction pattern of a circle is also gotten.In terms of the theory of color mixture and the superposition principle of colors displaying on computer screen,simulated interference pattern of white light Young′s experiment and simulated Fraunhofer diffraction pattern of a circle shined white light are realized by equivalent virtue of mixing three wavelength lights of 700 nm（red）and 546.1 nm（green）and 435.8 nm（blue）.The proposed method in this article can be used widely on discussing the physical phenomena related to visible light.
