摘要
仿生光学复眼具有体积小、重量轻、视场大、灵敏度高、可测速等优点,在国防尖端装备及民用工业中有着广泛的应用前景,因而引起国内外学者的广泛关注。简要分析昆虫复眼的特征原理,归纳仿生光学复眼的结构、功能及其分类;详细阐述国内外学者在仿生光学复眼优化设计和制造技术方面取得的最新研究成果,并通过对仿生光学复眼成像试验结果的综合分析与讨论,得出仿生光学复眼在采用微透镜阵列进行设计存在的缺陷以及采取特种加工方法制造等加工工艺存在的不足;论述仿生光学复眼采用截面六边形高次曲面进行设计的优点以及采取超精密加工方法制造存在的优势,给出研制过程中对其曲面进行造型与加工的新思路,可为光学复眼的进一步研究提供有益参考。
With the advantages of small volume,light weight,large field-of-view,high sensitivity and measuring speed,the artificial optical compound eye has broad application prospects in both advanced equipment of national defense and civilian industries and has attracted more and more attention.The characteristic of insects＇ compound eye is analyzed briefly and the structure,function and classification of compound eye are concluded;the new progress in both design and manufacture of artificial optical compound eye is discussed in detail;the disadvantage in design using the optical micro lens array and the deficiency in manufacture process,such as the special processing,are made clear through comprehensive analysis and discussion of the imaging test results of the artificial optical compound eye.The merits of designing optical compound eye by using cross-section hexagon higher-order curved surface and the advantage of manufacture by using ultra-precision machining technology are discussed.A new idea of modeling and processing of the curved surface is given in order to provide a useful reference for further study.
