摘　　要：本文在对高斯光束、艾里光束进行理论分析研究的基础上,基于SeeLight光学系统虚拟仿真实验平台,使用透镜实现傅里叶变换的操作,并分别改变波长、束腰半径、透镜焦距等条件,分析对实验结果的影响;基于MATLAB平台,对艾里光束进行了傅里叶变换,并改变衰减系数,分析其影响。通过观察傅里叶变换后的图像,可以总结得到高斯光束和艾里光束在频域上的性质,并分析各个实验因素造成的影响。Based on the theoretical analysis of Gaussian beam and Arie beam, the Fourier transform operation is realized by using lens on the virtual simulation platform of SheeLight optical system, and the influence of wavelength, beam waist radius and lens focal length on the experimental results is analyzed. The Fourier transform of Airy beam is carried out and the attenuation coefficient is changed to analyze its influence. By observing the Fourier transform images, we can summarize the properties of Gauss and Arie beams in frequency domain, and analyze the influence of various experimental factors.
