摘要: 利用基尔霍夫衍射公式通过数值计算绘制出理想狭缝在不同区域的衍射光强分布,并与菲涅耳衍射公式及夫朗禾费衍射公式的计算的结果比较,对基尔霍夫衍射公式、菲涅尔衍射公式和夫朗禾费衍射公式的适用范围做了详细的讨论.

关键词: 基尔霍夫衍射, 菲涅尔衍射, 夫朗禾费衍射

Abstract: The Kirchhoff's diffraction formula is used to draw the diffraction luminous intensity distribution of an ideal slit in the different regimes through numerical calculations.The numerical results are compared with the one by the Fresnel and Fraunhofer diffraction formula,the application range of the results is also discussed in detail.

Key words: Kirchhoff's diffraction, Fresnel's diffraction, Fraunhofe's diffraction
