dc.description.abstract | 本論文主要介紹利用曲面型多焦距微透鏡陣列來製作廣角相機模組,結合人眼和昆蟲複眼的概念來設計相機架構,並使用球面鏡和曲型微透鏡陣列來模仿人眼和昆蟲複眼。整個論文主要分為製作微透鏡陣列和架設相機模組。製程主要分成兩個部分: 平面多焦距微透鏡陣列的製作和將平面轉成曲面的翻模過程。製作微透鏡陣列的過程中,利用SU-8光阻與自身微疏水之特性,並使用噴墨機台製作平面的微透鏡陣列,再將平面的微透鏡陣列利用曲型模具翻印成曲面型的微透鏡陣列。我們製作出的微透鏡直徑是400微米,並設計四種不同焦距的微透鏡,做成微透鏡陣列,翻印在曲型表面,曲面的曲率半徑是2.45毫米,高度是1.08毫米。將製作完成的微透鏡陣列架設在光學系統中進行量測分析,利用圖像拼接和影像處理完成相片。我們的相機模組僅用了一個鏡片,厚度僅有2.08毫米,但可視角可達到100度。 | zh_TW |
dc.description.abstract | In this thesis, we presented a wide-angle and compact camera module that consists of microlens arrays with different focal lengths on curved surface. The design integrates the principle of an insect’s compound eye and the human eye. It contains a curved hexagonal microlens array and a spherical lens. The diameter of microlens is 400 µm, and we fabricate 4 groups different focal length of microlenses. The radius of curvature of curved surface is 2.45 mm and sag height is 1.08 mm. Compared with normal mobile phone cameras which usually need no less than four lenses, the proposed system use only one lens. Furthermore, the thickness of our proposed system is only 2.08 mm and full field of view is about 100 degrees. To make the critical microlens arrays, we used the inkjet printing to control the focal lengths of each microlens and use replication method to form curvature hexagonal microlens arrays. | en |
