  • This research demonstrated an innovative and integrated approach to design 3D compound eye optical structure which composed of seven sub-systems, and to improve image quality of marginal FOV. For every sub-system, it is an unattached optical system with cross light path, which consists of a mircolens array layer, an aperture stop array, and integrating freeform lens which are used to make images of different mircolens onto a plane image sensor. It's easier for this structure to get better image quality for marginal FOV by reducing the maximum light deviation angle. The theoretic FOV can be as large as 180. In the meantime the requirment for fabricating accuracy is not very high. The feasibility of the proposed structure is validated with optical software.
