摘要: 本研究目標為開發仿生複眼曲面微透鏡陣列,作為微小影像擷取裝置之實現。以微影技術與電鑄技術製作出平面微透鏡陣列模仁,並且以彈性透明膠(PDMS)為材料翻模,得到平面微透鏡陣列薄膜,接著製作一個上方開孔的PDMS腔體,將翻模後的PDMS平面微透鏡陣列薄膜倒置,黏貼於腔體上方成為密封腔體,接著用抽氣的方式使腔體內外壓力不同,導致平面微透鏡陣列變形為曲面微透鏡陣列,最後將曲面微透鏡陣列與CMOS影像感測器結合,完成微小影像擷取裝置,此系統的視場角可達到62°。本研究成功製作出同位的曲面微透鏡陣列,具有製程簡易、模仁可重複使用、成型快速等優點,開創此微小影像擷取裝置之核心技術。
The research goal is to develop a bionic compound eye with curved microlens array. It can be used as the implementation of miniaturized imagery capture systems. In this study, lithography and electroforming technology were used to fabricate planar microlens array mold insert and PDMS was the material for replicating planar microlens array membrane. Then the planar microlens array membrane was placed on a top opening chamber in PDMS (replicated from a plastic mold). The membrane was used to paste on the top opening chamber and formed a sealed chamber. A syringe was used to evacuate the air in the chamber and caused pressure difference in the chamber resulted in the membrane deformation. The deformed membrane with microlens array has the curvature to collect images. It was combined with the CMOS image sensor to capture images. The FOV of the system is 62. This study successfully fabricated the apposition microlens array, which have the advantages of simple process, the mold can be reused and rapid forming. The study explored the key technology for miniaturized imagery capture devices.
