摘要

针对大视场曲面仿生复眼透镜的制造难点

采用了一种基于气压辅助聚合物弹性体微复型的制造工艺

以实现大视场曲面微透镜阵列的快速、低成本制造。利用有限元软件(ABAQUS)

对气压辅助微复型工艺过程中聚合物弹性体的大变形、曲面成型过程中微透镜的形变问题进行了仿真实验

得到了曲面成型过程中曲面轮廓对成型气压的依赖关系

以及不同纬度微透镜阵列的尺寸变化关系

并进行了相关工艺实验验证。结果表明

在气压辅助曲面成型过程中

成型曲面的轮廓为球面

其球面直径依赖于成型气压; 曲面成型过程中

微透镜形变量沿曲面纬度方向基本一致

不同纬度上微透镜直径的增大率为9.45%～10.56%。由于在不同纬度处所制造的曲面复眼透镜的焦平面不同

因此曲面复眼透镜具有比平面微透镜阵列更大的视场。

Abstract

Focusing on the difficulty of manufacturing curved bionic compound lens with big field of view

a manufacturing process based on the pneumatic auxiliary micro-replication of polymer elastomer is proposed to realize fast and low cost production of bionic compound eye. Then ABAQUS software is adopted to analyze the large deformation of polymer elastomer and microlens deformation problems in gas-assisted micro-replica process

and the dependence of surface profile upon the molding pressure and size variation of mircrolens in different sphere latitude are revealed and compared with the experiments. During curved surface forming

the surface profile gets spherical whose diameter depends upon the molding pressure; the deformation rates of microlens along the sphere latitude remain equal

and the microlens diameter on different latitude increases by 9.45% to 10.56%. The curved bionic compound lens possesses different focal planes along the sphere latitude and larger field of view than planar microlens array.
