Characteristics of Axial Light Intensity of Planar Wave Diffracted by Small Circular Aperture
Based on the accurate diffraction formula and the accurate expression of light intensity on the transverse plane, the characteristics of axial light intensity of planar wave diffracted by small circular aperture are investigated. Variation relations of the maximum axial light intensity and the numbers of light extremum versus the radius of small circular aperture are given. The application condition of general Fresnel number formula is also studied.
