  • In this paper,using the generalized Huygens Fresnel diffraction integral and statistical optics method,the propagation properties of laser beams with amplitude modulations and phase fluctuations passing through hard-edged and soft-edged apertures have been studied in detail.Numerical calculation results have illustrated that the intensity distributions in the near and far fields are dependent on the truncation parameter,Fresnel number of the system,and parameters of amplitude modulations and phase fluctuations.
