| Abstract: | In this paper,starting from the Fresnel-Kirchhoff diffraction integral formula,the Fresnel single-slit,double-slit as well as multi-slit diffracted light intensity distribution was calculated through numerical integration and mapping out its light intensity distribution curve.While the specific expression to calculate the light vibration distribution of Fresnel multi-slit diffraction was also provided.The studying result is of great theoretical significance to grasp Fresnel diffraction. |
