摘要

本研究以可變曲率的液態變焦透鏡原理為基礎在鏡組結構上進行設計及製造一個廣角鏡組。借鑒Hologon和Cooke Triplet之鏡組結構，設計了一組具三片式的可變曲率的液態鏡組。而在分析及設計時液態透鏡所用之折射液的光學特性仍基於美國Cargille Lab研製的高素質折射液；並以此特性在ZEMAX上完成鏡組的設計和模擬分析。鏡組的材料採用PDMS材料與玻璃材料混合使用，並將折射液填充其中。通過控制液體壓力變化來改變PDMS薄膜的曲率，從而實現改變鏡組視角範圍的目的。最終目標是設計一個可從超廣視角變成常規視角的液態透鏡鏡組，並製作出來以驗證理論設計是可行的。

This research is focused on the configuration design of a wide angle variable curvature liquid-filled lens system. Refering the configuration of the Hologon and Cooke-Triplet, the design of the lens system is three-piece lens. The liquid used in liquid lens is the high quality optical liquid from Cargille Labs. The design and analysis tool is the ZEMAX. The lens is made by glasses and PDMS, with the optical liquid filled in. By controlling the pressure of the liquid, the curvature of the PDMS membrane could be controlled, and the view of the lens could be changed. The target of this research is to finish the design of the liquid-filled lens, which can be changed from the wide angle to the normal focus, and a system according to the design results will be set up to verify the theory and reality.
