Simulation and analysis of the rectangular hole diffraction irradiated by a monochromatic point source

To explore the rectangular hole diffraction irradiated by a point source,firstly the integral expression for the rectangular hole diffraction irradiated by a monochromatic point source is deduced,and then the light field of the rectangular hole diffraction irradiated by a monochromatic point source is simulated with the MatLab software.This is helpful in the actual diffraction experiment and the study of the correlation theories and technologies.
