中文摘要： 人工复眼结构由曲面上密集排布的子眼组成，其中子眼结构的面形通常为二次曲面或者高次曲面以获取高质量的成像效果。这种体积小，子眼数多，曲面密集排布，面形要求严格的结构给制备技术带来了极大的挑战。针对该问题，本项目提出“拓扑映射法制备成像级人工曲面复眼结构及面形控制研究”。通过引入新材料新工艺，将二维平面微透镜列阵结构拓扑转移到曲面上成型人工复眼结构。通过研究二维平面结构与三维曲面结构之间的拓扑映射关系，并对拓扑转移过程中产生的变形量进行研究和标定，实现面形控制，最终在曲面基底上制备出集成化、小型化、轻量化的成像级人工复眼结构，使其面形误差小于5%，成像效果MTF曲面趋近衍射极限。该复眼通过与后端的探测器及电路结构相互联，可进一步实现具备大视场探测、高精度定位等功能的光、机、电一体化复眼成像系统的研制。该技术可在普通实验室实施完成，不涉及昂贵的设备和仪器，研制成本低，普适性强。

英文摘要： Artificial compound eye structure consists of densely arranged on the surface of the sub-eyes , of which the sub- surface of the eye -shaped structures typically quadratic surface or surface to obtain higher quality imaging results. This small volume, large number of sub-eyes, dense surface arrangement, strict surface shape demand structure has brought great challenges to the fabrication technology. To.solve this problem , the project propose the study of a topology-mapping method and profile control technology used to fabricate imaging artificial compound eye. Through the introduction of new materials, new technology , the two-dimensional plane microlens array structure formed on the plane surface is topology transferred to the curvature surface to fabricate artificial compound eye. By studying the topology-mapping relationship between the two-dimensional structure and the three-dimensional structure, the amount of deformation generated in the topology transfer process is research to calibrate the shape deform and realize shape control. Finally a technology will developed for preparing the integration , miniaturization , lightweight artificial compound eye with surface.error of less than 5% and the imaging results MTF curved approaches the diffraction limit . The compound eyes with the back-end of the probe and the circuit structure of interconnectedness can be further achieved with the large field of exploration, high-precision positioning and other functions of optical ,mechanical and electrical integration of compound eye imaging system. The technology can be implemented in an ordinary laboratory, does not involve expensive equipment and instruments, which is low cost, wide range of.applications.
