摘　　要：在教学实验中,由于受到衍射物加工精度和相机灵敏度的限制,常常不能明显地观察到与理论相匹配的菲涅耳衍射图样.本文先利用VirtualLab Fusion虚拟仿真平台计算出不同尺寸圆孔与圆屏在不同位置的菲涅耳衍射图样,再进一步针对特定尺寸圆孔与圆屏分别进行了光学实验、仿真计算以及理论预测,并对结果进行了对比分析,这将有助于增强教学效果.In teaching experiment,Fresnel diffraction pattern that matches the theory cannot be frenquently and obviously observed due to the limitation of diffracting object processing precision and camera sensitivity.In this paper,VirtualLab Fusion simulation platform is used to calculate and simulate Fresnel diffraction patterns of circular aperture and stop with different sizes and different observing positions.Then the optical experiments,simulation calculations and theoretical predictions are carried out for circular apertures and stops with specific sizes respectively,and then all results are analyzed and compared with each other.It is believed that this will help to enhance teaching effectiveness.
