本論文主要研究是利用聚合物曝光法製作共軸雙焦液晶透鏡陣列，並將所製作之元件應用在積分成像系統(Integral imaging system)中以改善立體影像之景深能力。在本研究中透過額外製作之介電層與不對稱水平液晶配向製作液晶透鏡陣列，其性能表現具有無不連續線產生、短焦、低操作電壓及較佳的干涉條紋等特徵。製程中添加光聚合物於液晶盒中，並施以光罩曝光使液晶透鏡單元之外圈區域之液晶分子具固定方向分佈而產生一固定焦距，而液晶透鏡單元之內圈區域之液晶分子可以隨電壓操作產生可調變焦距，如此，完成共軸雙焦距之液晶透鏡陣列製作。
在共軸雙焦液晶透鏡陣列應用於積分成像系統之研究中，是藉由模擬軟體產生包含空間中不同位置的兩物體訊息之影像單元，分別以一般液晶透鏡陣列與具共軸雙焦特性之液晶透鏡陣列重建其立體影像，比較其兩者不同的重建影像結果，可得到共軸雙焦液晶透鏡陣列具有較一般液晶透鏡陣列約2.4倍之景深範圍，驗證了本研究之透過聚合物曝光法達成之共軸雙焦液晶透鏡具有提升在積分成像系統中重建立體影像的景深範圍能力之目的。

In this study, a tunable coaxially bifocal liquid crystal (CBLC) lens array is investigated and demonstrated via photo-polymerization processes. Due to specifics of electrically tuning bi-focuses in the CBLC lens array, it will provide two central depth planes to improve depth of field (DoF) in the integral imaging (InIm) system. In this study, significant enhancements of DoF have been demonstrated and confirmed by means of the fabricated CBLC lens array in the InIm system. As a result, an optimal enhancement of DoF is 6 cm, which is 2.4 times lengths than that by means of a single focus LC lens array.
