采用严格的矢量衍射理论,研究了平面光波垂直入射微小的圆孔光阑后的近场衍射光强的空间分布,模拟计算了衍射光强的空间分布.Matlab 仿真结果表明,近场衍射既属于菲涅耳衍射,又接近于夫朗和费衍射.
採用嚴格的矢量衍射理論,研究瞭平麵光波垂直入射微小的圓孔光闌後的近場衍射光彊的空間分佈,模擬計算瞭衍射光彊的空間分佈.Matlab 倣真結果錶明,近場衍射既屬于菲涅耳衍射,又接近于伕朗和費衍射.

With rigorous vector diffraction theory,the light intensity distribution of near-field diffraction for planar light waves with vertical incidence diffracted at small circular aperture is studied,and the spa-tial distribution characteristics of the diffraction light intensity simulation is calculated by computer.The Mablab simulation results show that the near-field diffraction belongs to Fresnel diffraction,and similar to Fraunhofer diffraction.
