摘要
提出了一种人工复眼结构的制备技术。人工复眼结构是由类似于昆虫复眼的很多小眼组成。这些小眼分布在球冠基底上以能够像昆虫复眼一样实现大视场探测。通过分析不同制备技术的特点及适用范围,研究材料的特性以及不同材料之间的关系,并将各种制作工艺以及材料相融合,发展了一种可用于制备曲面微阵列元件的制备方法。在该方法中,利用微加工技术在平面上制备作为子眼的微透镜列阵结构;然后利用软光刻技术将该微透镜结构进行翻模,获得分布在柔性基底上的凹透镜列阵结构;最后利用浇铸复制技术将柔性基底上的结构转移到球冠基底上,获得所需的人工复眼结构。利用该方法,开展了相关实验,在曲面基底上制备出了包含20 000多个子眼的人工复眼结构。
A method used to fabricate artificial compound eye was presented in this paper. The artificial compound eye is composed of ommatidia like that of an insect＇s compound eye. By studying the characteristic of different fabrication technique, analyzing the performance of materials and relationship between different materials, and composing the fabrication techniques and materials together, a method to manufacture micro array elements based on curvature substrate was proposed. In this method, microlens patterns used as ommatidia were fabricated by regular micro-fabrication. Soft-lithography was used to manufacture the deformed elastomer membrane to obtain opposite concave microlens patterns. Polymer replication was used to transfer the patterns onto the hemispherical dome substrate. Experiments were carried out and an artificial compound eye contain over 20 thousands ommatidias were fabricated.
