對方形小孔徑近場繞射光強度分布函數之計算

A Study of an Intensity Distribution Algorithm for Rectangular Aperture Near-Field Diffraction

摘要


本文提出詳細計算於單色光均勻照射下,方形小孔徑在Fresnel近場繞射中光強度分布函數之新的演算法,並以新的計算方式比對在同條件下Fraunhofer遠場繞射因孔徑因素而衍生之像差問題。

並列摘要


This study develops new explicit calculation methods concerning the distribution function of the light intensity of a rectangular aperture within a Fresnel near-field diffraction under monochromatic light illumination and makes some comparisons with the problems with the image aberration of Fraunhofer far-field diffraction due to the aperture factor.
