Abstract: 人的眼睛是一個簡單的光學結構,擁有自由變焦的能力,同時具有不錯的解析度,缺點是代表影像感測器的視網膜是曲面的形狀。而複眼結構有極為廣大的視角,有極高的時間解析度,但通常空間解析度很差。在真實相機系統中,由於製程上的限制,很難設計出同時含有眼睛各種優點的光學系統。在本篇論文中,我們提出了一種結合昆蟲複眼以及人眼特性的相機鏡頭設計,以微透鏡陣列來模擬複眼的結構,加上兩片主透鏡模擬人眼水晶體來達到廣視角的效果。相較於市面上視角不大且使用五片以上透鏡的手機相機鏡頭來說,本設計擁有更小的體積以及更大的視角。由於微透鏡陣列製作技術日漸進步,這種成像系統在強調輕薄的智慧型手機上擁有更大的優勢。
The human eye has simple structure, high resolution but curved retina. On the other hand, the compound eye has wider field of view but low resolution. In this thesis, we proposed a camera lens design combining with the principle of the insect compound eye and the human eye, simulating the compound eye structure by the microlens array and using two main lenses to simulate human’s lens. This system maintains the advantages and removes the shortcomings of the two structures. Comparing with the mobile phone camera lens with more than five lenses structure and limited field angle, this design contains 6.2 mm × 4.6 mm image plane size with small thickness (5 mm); large field of view (120°
