摘要
基于光的衍射与干涉理论,利用Matlab软件计算了孔数目为1～6的螺旋孔屏的光场光强与相位涡旋分布.手工制作了孔数目为1～6的螺旋孔屏,搭建了马赫-曾德尔干涉光路,获得了各螺旋孔屏产生的光场与参考光的干涉光强,实验结果与数值计算结果基本一致.
Abstract
Based on the theory of diffraction and interference of light,Matlab program was used to numerically calculate the optical field intensity and phase vortex distribution of spiral hole screens whose hole numbers ranges from one to six.Spiral hole screens with 1～6 holes were handmade.Mach-Zehnder interference optical path was constructed.The interference intensity between the light field generated by each spiral hole screen and the reference light was experimentally obtained.The ex-perimental results were almost identical to the numerical calculation results.
