| 摘 要： | 用广义惠更斯-菲涅耳衍射积分和统计光学方法对有振幅调制和位相畸变光束分别通过硬边和软边光阑的传输特性作了详细研究。数值计算结果表明近场和远场光强分布与截断参数、系统菲涅耳数、光束的振幅调制和位相畸变参数均有关。

Changes of laser beams with amplitude modulations and phase fluctuations passing through an aperture |
| |
| Abstract: | 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. |

| Keywords: | laser beam with amplitude modulations and phase fluctuations hard edged aperture soft edged aperture near field far field |
