根据夫琅禾费衍射与傅立叶变换的关系,数值计算了由宽度相同而长度不同双缝组成衍射平面的夫琅禾费衍射光强分布,结果表明双缝长度之比是影响干涉条纹的可见度的主要因素。
根據伕瑯禾費衍射與傅立葉變換的關繫,數值計算瞭由寬度相同而長度不同雙縫組成衍射平麵的伕瑯禾費衍射光彊分佈,結果錶明雙縫長度之比是影響榦涉條紋的可見度的主要因素。

According to the relationship between Fraunhofer diffraction and Fourier transformation, the Fraunhofer diffraction light intensity distribution of the double-slit with equality wideth but inequality length is nume- riacally calculated. The result shows that the proportion of the length of the double-slit will mainly affect the visibility of the interference fringe of the double-slit.
