【摘要】：研究了方形孔径平面微透镜阵列和微图形阵列的叠栅条纹的傅里叶原理。方形孔径平面微透镜阵列可视为正交的二维栅格线簇,以一维光栅叠栅条纹的傅里叶变换原理为基础,推导了方形孔径平面微透镜阵列二维叠栅条纹的傅里叶变换解析式,对低频(1,-1)级叠栅条纹进行详细讨论。同时对不同夹角下叠栅条纹的周期和同步性进行重点研究,并采用不同结构参数的二维栅格模板与微图形阵列进行实验,结果表明:实验值和理论值相吻合,研究结果为方形孔径平面微透镜阵列的应用与研究提供了理论基础。
[Abstract]:The Fourier principle of grid fringes of square aperture planar microlens array and micrographic array is studied. The square aperture plane microlens array can be regarded as an orthogonal two-dimensional grid line cluster. Based on the Fourier transform principle of one dimensional grating superimposed grid stripes, the Fourier transform analytic formula of square aperture plane microlens array two-dimensional stacked grid stripes is derived. The low frequency (1 ~ 1) cascade fringes are discussed in detail. At the same time, the period and synchronicity of the fringes under different angles are studied emphatically. The experimental results show that the experimental values are in good agreement with the theoretical values, and the two dimensional grid templates with different structure parameters are used to carry out the experiments with the micrographic arrays. The results provide a theoretical basis for the application and research of square aperture planar microlens array.
