本文通过结构性设计解决了曲面复眼光学系统边缘视场像质难以提高的问题。该光学系统由7个相互独立的子复眼光学系统组成，各子复眼光学系统相互独立，其光线相互交叉。在系统中引入自由曲面透镜，自由曲面透镜相当于棱镜将微透镜阵列光线偏折，使同一子系统的微透镜成像于平的像面上。每个子系统包括一层微透镜阵列，一个自由曲面透镜，一光阑阵列和后续像差校正镜。相比较于传统的复眼系统，该结构对复眼边缘视场的像差校正能力更强，能很大程度地提高边缘视场的像质。该系统的理论视场可达180°，制造精密要求不高且适用性强。本文最后通过光学软件zemax对光学系统进行了模拟验证，证明其可实现性。

This research demonstrated an innovative and integrated approach to design 3D compound eye opti-cal 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 soft-ware.
