| Abstract: | The distribution formula of relative diffraction intensity of different triangular and quadrangle apertures Fraunhofer diffraction on the screen was derived by Kirchhoff diffraction theory.Fraunhofer diffraction pattern and relative intensity distribution of different triangular and quadrangle apertures were simulated by mathematica software,which revealed the relationship between different shapes of triangular and quadrangle apertures,and Fraunhofer diffraction pattern. |
