| Abstract: | Take the diffraction by circular aperture for example. The Fresnel's integration of plane screen's diffraction was computed with Gauss's integrating method, and the light intensity of arbitrary point in Fresnel's diffractive field was got, when the small circular aperture,was lighted by homogeneous spot source. |
