Integral photography (IP) 技術是一種近年來被逐漸重視的全像技術,藉由微小化透鏡陣列(MLA)鏡頭,可將透過某一平面的光線加以捕捉,並藉其重現原始物體之部分三維(3D)影像,由於使用此種三維全像技術所重建之影像,於觀察時並不需要使用特殊偏光鏡片,所以IP在於三維全像顯像上是相當理想的技術。本篇論文藉由先進系統分析程式(ASAP),建立快速而可靠的IP系統分析方式,並藉由參數之最佳化分析,提出最大解析度暨最大視角的改善方式。

Integral photography (IP) can be regarded as a method of capturing and displaying light rays passing through a plane. Because a three-dimensional (3-D) autostereoscopic image can be seen from a designed viewpoint without any special viewing glasses, IP is an ideal method to create 3-D autostereoscopic images. The conventional IP method in which is placed the film or a CCD camera behind a lens array immediately. In this thesis, the author proposes a method of analyzing maximum resolution and viewing angle from IP images simulated by the ASAP software, which enables us to getting optimum reconstruction image quality. Final simulated results show the potential to build the whole IP optical system by computer simulation technologies.
