| Abstract: | Based on Kirchhoff diffraction integral formula, and the relations of curve coordinate and the known Fraunhofer diffraction of rectangle were utilized, the exact solution of Fraunhofer diffraction of aperture constructed with regular hexagon and rectangle was deduced. Matlab software was used to demonstrate and analysis the light intensity distributions of aperture constructed with regular hexagon and rectangle, and some conclusions were obtained. |
