白光夫琅和费衍射实验的计算机仿真

Computer Simulation of White Light Fraunhofer Diffraction Experiments

以日光为白光光源,把日光的可见光谱均匀分割为2 000份色光,计算出各色光的RGB代码。基于Matlab软件实现了白光夫琅和费圆孔、矩孔及单缝衍射实验的计算机仿真。结果表明,这些白光夫琅和费衍射实验的仿真图像色彩连续、细腻而与实际实验的结果一致,能直接投影于多媒体屏幕上,可应用于光学辅助教学等领域。

Taking sunlight as white light source,the visible spectrum of sunlight was divided into 2 000 uniform chromatic lights,the RGB code values of these chromatic lights were calculated.Based on Matlab,the white light Fraunhofer diffraction experiments of circular aperture,matrix aperture and single slit were simulated.The results show that,the colors of simulation pictures of these diffraction experiments are sustainable and exquisite.These simulation pictures are consistent with the results of actual experiments,and can be connected to the multimedia screen directly and applied in the fields such as optical computer aided instruction.
