摘要
大孔径仿生复眼光学系统兼顾了凝视大视场的同时, 克服了生物复眼孔径小、视距短的缺陷。通过对仿生复眼视场拼接方法的分析, 研究了实际阵列周期与理论计算周期数的关系, 并提出了降低子眼系统密度的填补子眼法。通过研究球面固定本体设计中的几何关系, 建立了本体径向半径d与曲率半径R的数学关系, 提出了球面固定本体的设计方法, 完善了之前提出的仿生复眼视场拼接理论。通过实际的装调实验, 验证了设计方法的正确性。利用该方法可提高仿生复眼系统的集成性, 减小系统尺寸, 推动了仿生复眼光学系统的实际应用。
Abstract
The large-aperture bionic compound eye optical system can have a large field of view, it overcomes the defects that the aperture of biological compound eyes is small while the vision distance is short. The relationship between the actual array period and theoretical calculated period number was researched through analyzing the field stitching method of bionic compound eye, the method called "padding sub eye method" was proposed to reduce sub eye configuration density. By studying the geometry relationship of the fixed spherical body design, the mathematical connection between the main body vertical radius d and the curvature R was established, the design method of fixed spherical body was proposed, and the proposed bionic compound eye field stitching theory was perfected. Finally, the correctness of the design method through the actual alignment experiments was verified. This method can improve the integration of the bionic compound eye system, reduce system size, and promote the practical application of bionic compound eye optical system.
