仿生复眼结构的制作与测试研究

为了更好地利用生物复眼的光学性能，介绍了一种新型仿生复眼结构。通过使用传统光刻胶热熔法和NOA73紫外曝光固化技术，得到了NOA73和PDMS材料的微透镜阵列，比较了它们的聚焦效果和光强分布，得到NOA73材料具有更好的光学性能；然后利用PDMS的柔韧性进行了两次倒模，再通过紫外曝光把NOA73固化，得到了背靠背形式的仿生复眼结构；最后对结构进行了成像测试、光强分布测试，并对结果进行了仿真和理论分析，可知该结构具有良好的形貌，光损耗小，光学性能优异并且具有很好的重复性，制作简单，成本低，能够模仿生物复眼的部分光学特性。

Fabrication and Test Study of Bionic Compound Eye

This paper presents a novel biomimetic compound eye structure in order to make better use of biological compound eyes’optical properties. We have made NOA73 and PDMS micro-lens array by using conventional photo?resist melting method and NOA73 UV curing technology,and certificated NOA73 has better optical performance by comparing their focusing effect and the light intensity distribution. Then using the PDMS flexible characteristics and NOA73 UV curing properties to make the back-to-back bionic compound eye structure. Finally making imaging tests,intensity distribution tests,simulation and theoretical analysis,the result shows that the structure has a good morphology,small optical loss,excellent optical performance and good reproducibility. It is simply made,low cost, and capable of imitating the part of optical properties of biological compound eyes structure.
