摘要
从惠更斯-菲涅耳原理出发,通过理论计算得到单缝衍射光强的分布公式,利用Fortran软件编程及Origin6.0 Professional软件画图模拟实现了光强在接收屏上的分布,讨论了缝宽、光波波长以及屏与缝之间的距离对衍射结果的影响.该数值分析结果与实验室实测结果一致,从而验证了单缝衍射光强分布公式的正确性.
Studying from the Huygens-Fresnel＇s principle, the formula is obtained which is about the light intensity distribution of single-slit diffraction through the theoretical calculation, numerical simulation＇s results has been gotten about the distribution of light intensity on the receiving screen by using FORTRAN software programming and Origin6.0 professional software, impact on diffraction from the slit width, wavelength and the distance between screen to slit have been discussed. This numerical analysis result is consistent with the laboratory actual result, and thus,correction of light intensity distribution of single-slit diffraction formula is verified.
