摘　　要：针对微透镜阵列成像时单元图像间存在的串扰问题,文中基于矩阵光学理论,分析了经微透镜阵列成像像面与物面的空间关系,模拟计算2×2的微透镜阵列成像,设计了焦距为7 mm的1×2阵列进行实验研究。研究结果表明:单元图像间距随微透镜焦距和物面尺寸的增大而减小,随微透镜间距和物距的增加而线性的增大。对于焦距为7 mm的微透镜,物距为40 mm,当物面尺寸为55 mm×55 mm时,获得了单元图像恰好分离的临界值,实验结果与模拟计算的理论值一致,该结果对设计微透镜阵列的成像系统具有一定的参考价值。The study aims to solve the crosstalk between unit images in microlens array imaging.Based on the matrix optics theory,the spatial relationship between the image plane and the object plane in imaging by microlens arrays was analyzed,the imaging by 2×2 microlens arrays was simulated and calculated,and a 1×2 array with a focal length of 7 mm was designed for experimental research.The results show that the image spacing of the given unit decreases with the increase in the focal length of the microlens and the size of the object plane,and increases linearly with the microlens array spacing and object distance.Finally,for the microlens with a focal length of 7 mm and an object distance of 40 mm,when the object plane is 55 mm×55 mm,the critical value of unit image separation is obtained.This experiment result is consistent with the theoretical values of simulation calculation.This study is of some value in the design of imaging system of microlens array.
