Compared with the traditional imaging systems, segmented planar imaging technology has the advantages of low mess, small size, and low power in the same resolution situation. To obtain relatively complete frequency domain coverage, the lenslet array requires a large number of lenslets, and the photonic integrated circuit board requires a large number of optical devices, which limits the application and development of the segmented planar imaging technology. In this paper, we introduce a novel, to the best of our knowledge, design of the photonic integrated circuit to ensure that each lenslet in the lenslet array can form a baseline with any other lenslets. This breaks the barrier between segmented planar imaging technology and the traditional synthetic aperture, giving segmented planar imaging technology a sufficient number of frequency domain samples and a concise photonic integrated circuit structure.
