Based on the visual advantages of bionic compound eyes, the research progress of bionic compound eyes was analyzed, and the imaging principle of compound eyes and the structure of some insect compound eyes were studied. According to the structure of the biological compound eye, a hexagonal closely spliced curved micro-lens array and image transfer system were designed. At the same time, in order to prevent the crosstalk of imaging beams between adjacent sub-eyes, an aperture array with a single aperture of 1.5 mm in length was designed to realize single-channel imaging of each sub-eye. According to the principle of pupil connection, the micro lens array and the conversion system were combined and optimized. The diameter of the entire compound eye was 8.66 mm, the field of view was 121°, the diameter of each sub-eye was 500 μm, and the field of view of the sub-eye was 6°. At 90 lp/mm, the MTF value of the compound eye system was greater than 0.3, and the RMS spot radius were less than the radius of the Airy disk, the imaging quality of the system meet the requirements of the design index. In order to met the requirements of 3D additive manufacturing process, the mechanical structure of the compound eye system was designed. The tolerance analysis result shows that the system structure meets the preparation requirements of 3D printing technology.
