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 X 2 microlens arrays was simulated and calculated,and al 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 mmX55 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.
