本論文研究如何製作無不連續線的液晶透鏡陣列,並將其應用於積分成像系統(Integral imaging system)中,觀察其立體影像的成像品質及相關特性。研究中首先討論各種製程方法對於避免不連續線的影響程度,透過「加入額外介電層法」、「混合配向法」、「光聚合穩固配向法」的互相比較,找出最佳的製程參數以製作無不連續線的液晶透鏡陣列。實驗結果利用加入介電層法及不對稱水平配向法成功製作出了無不連續線的液晶透鏡陣列,其最短焦距可達0.7 cm,操作電壓約在4~15 Vrms。
其次將無不連續線的液晶透鏡陣列應用於積分成像系統中,找出最佳的成像距離位置,並量測出可視角範圍約4.5˚。最後驗證了方位視差(Motion parallax)效果,以及比較液晶透鏡陣列有無不連續線時的影像品質狀況。相較於本實驗室過往的研究結果,本研究方法製作的液晶透鏡在成像品質及聚焦能力上皆有良好的表現。
In this thesis, a few ways used to fabricate liquid crystal lens arrays without disclination line issues are investigated. Simultaneously, free disclination line liquid crystal lens arrays are demonstrated their optical performance in integral imaging system. Comparing experimental results for preventing disclination line occurrence among the executed ways, a fabrication way with an extra dielectric layer in asymmetric homogeneous cells is an optimal choice to successfully fabricate free disclination line LC lens arrays. The completed LC lens array shows its minimum focal length of 0.7 cm when operating voltages in the range of 4~15 Vrms.
The optimal LC lens array is also used in integral image system to demonstrate autostereoscopic performance. As a result, it achieves capability of viewing angle about 4.5˚ for autostereoscopic images and obvious motion parallax performance. In conclusion, free disclination line LC lens arrays in this study show better optical performance than that in previous work.
