Segmented planar photoelectric imaging is an advanced computational technology that utilizes photonic integrated circuits (PICs) to achieve the miniaturization of systems. The original radial-spoke lens array has dense radial sampling and coarse azimuthal sampling. sparsity inhomogeneity spatial frequency lead loss information blurred reconstructed images. In this paper, a honeycomb azimuth proposed, three baseline pairing methods are designed, which can realize sampling, effectively increase improve quality. signal transmission model segmented system established process simulated analyzed. simulation results show improves density coverage, its quality significantly improved compared with hexagonal array. Furthermore, optimal choice method error range fill factor also given in paper. indicate mixed first ensures low medium-frequency then increases high-frequency makes better than those other two terms image contour, contrast detail information. be by increasing factor. actual manufacturing process, allowable within 5%. research will provide theoretical support for design development system.
