    摘要: 本研究探討稜鏡陣列立體拍攝系統優化設計,採用優化技術結合CODE V光學軟體使用者自訂的巨集指令,來設計稜鏡陣列及光學鏡頭達到3D立體拍攝的目的。本文提出兩種設計方法,第一種為稜鏡陣列結合光學鏡頭優化設計,採用視角對稱式稜鏡陣列可以消除軸上色差,輔以光學鏡頭消除離軸色差;在消色差雙稜鏡陣列及光學鏡頭優化設計方面,結果顯示系統優化後的橫向色差最大值為1.3 µm,最大光學畸變絕對值為12.27%。第二種為通用型稜鏡陣列優化設計,此設計係固定鏡頭參數下僅對稜鏡陣列的參數進行優化設計,藉此設計可以適用於各式光學鏡頭,而為達此目的提出立體影像中心法(stereo-image center method),可以增加稜鏡的視角且可降低色差。若再配合消色差雙片稜鏡陣列組設計,則可大幅降低色差。此外,本文也提出消畸變微結構稜鏡陣列的優化設計方法可以有效改善畸變。;This study presents the optimization design of stereo-photography system based on prism array. The optimization technique combined with CODE V optical software user-defined macro function to design the prism array and optical lenses to achieve the purpose of 3D stereo-photography. In this dissertation, two optical design methods are proposed. The first one is the optimization design of prism array and optical lenses. The viewing-angle symmetric prism array can eliminate the on-axis chromatic aberration, and optical lenses eliminate the off-axis chromatic aberration. In the optimization design of achromatic dual-prism array and optical lenses, the results show that the optical system after optimization has the maximum lateral chromatic aberration of 1.3 m and the absolute maximum optical distortion of 12.27%. The second is an optimization design of general-purpose prism array. The design parameters of the optical lenses were fixed, the prism array was only used to optimize the system design, which can be applied for various types of optical lenses. To achieve this objective, a stereo-image center method was proposed to increase the viewing-angle and to reduce chromatic aberration. If the achromatic double-prism array design was used, the chromatic aberration could be reduced significantly. In addition, the optimization design of the distortion-reduced prism array with micro structure elements was also proposed to improve the distortion effectively.
