Description
Summary:碩士 === 國立成功大學 === 光電科學與工程學系 === 104 === 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.
