【Abstract】 The light intensity distribution of diffraction of circular aperture was investigated by numerical analysis.In the case of the light intensity distribution function according to the boundary diffraction wave theory formula scaled along the axis direction of light intensity respectively in the shadow zone and the geometrical zone,then by comparing the above light intensity distribution curse and one directly by using the dualistic integral,the accuracy of the boundary diffraction wave theory formula was analyzed in some certain areas.更多还原
