本論文主要研究於改善液晶透鏡之反應時間，液晶透鏡為利用圓孔型電極在液晶層產生非均勻性對稱電場，造成液晶分子方向成一折射率梯度分佈，當入射光進入液晶透鏡時，感受到不同的光程差進而造成光線的匯聚或發散；而我們利用參雜聚合物於液晶當中加快液晶透鏡之反應時間，具體的方法是先施加電壓將液晶定於最大干涉條紋分布，再替換圓孔型電極為整面電極將液晶分子轉向於垂直電場平行，藉此得到最大的可調焦距範圍。
在實驗中發現，圓孔的孔徑大小與液晶層厚度對於可調焦距範圍互相影響，就目前的實驗結果來看，上升反應時間為97ms，下降反應時間為8.5ms，但是可調焦距均在120cm以上(130~152.8cm)，嚴重影響液晶透鏡的透鏡能力。

In this thesis, the main investigation is to fabricate electrically switchable fast response liquid crystal lens via prior generation of polymer networks. We mixed polymer in liquid crystal lens to accelerate the response time by way of setting the liquid crystal in the most distribution of interference fringes, then using the vertical electric field which is to change the hole pattern electrode to the entire surface of the electrode to stretch the liquid crystal.

As a result, the aperture of the hole pattern and cell gap make the impact on adjustable focal length range. Although we achieve a good response time, but the adjustable focal length range are almost above 120cm, the image quality have deterioration severely.
