中文摘要 本論文主要研究共平面內浮動圓環孔型電極液晶透鏡陣列(coplanar inner floating ring hole-patterned electrode liquid crystal lens arrays, CIFR-HPELCLA),並根據其對應之等效電路模型,探討浮動圓環孔型電極液晶透鏡陣列之結構參數對操作頻率與電壓之影響,並藉由調整NOA65介電層厚度產生電容值改變以改善液晶透鏡之性能,最後將所製作之液晶透鏡陣列應用於積分成像系統(Integral Imaging system)上,探究其性能表現。
實驗製作的共平面內浮動圓環孔型電極液晶透鏡與傳統圓孔型電極液晶透鏡皆是透過施加電壓於液晶層,產生軸對稱的非均勻電場分佈(Fringing field),使液晶分子轉動形成折射率梯度分佈,當光通過液晶透鏡可達到匯聚或發散的能力。共平面內浮動圓環孔型電極製程簡單,在傳統圓孔型電極中增加一同心圓環浮動電極,使液晶透鏡中心亦產生電場分佈,透過等效電路模型可知兩者對液晶分子方向分佈與相對應的透鏡能力之差異。
共平面內浮動圓環孔型電極液晶透鏡陣列與傳統圓孔型電極液晶透鏡陣列,經過NOA65介電層厚度之影響、焦距量測、波前誤差、調制轉換函數值(Modulation Transfer Function,MTF)評估與應用於積分成像系統之影像等比較之下,可發現確實改善了整體液晶透鏡的能力。
英文摘要 A type of liquid crystal lens array composed of lens units with hole-patterned electrode inside a coplanar inner floating ring electrode (CIFR), briefly nemed as CIFR-HPELCLA (i.e., coplanar inner floating ring hole-patterned electrode liquid crystal lens array) was investigated. The electric circuit model was used to analyze and discuss the CIFR electrode affected the overall performance of CIFR-HPELCLA. We did experiments to compare the electro-optical performance between the traditional HPELCLA and CIFR-HPELCLA including electrically driving frequencies, voltages, and the thicknesses of the dielectric layer. Finally, both of HPELCLA and CIFR-HPELCLA were applied to the integral imaging system to compare their individual image performance.
