Abstract (in Japanese) (See Japanese page) 
(in English) Liquid crystal (LC) materials exhibit anisotropies regarding their electrical and optical properties. LCs combine the properties of solids and isotropic liquids and exhibit the electro-optical phenomenon. The LC molecules can be easily reoriented by an externally applied electric field. In this study, we propose an LC lens with transparent-multi-ring-electrodes and a highly-resistive film. The interference fringe images of the LC lens can be observed by a polarizing system under cross polarizers when an appropriate voltage is applied to each ring electrode. The optical phase profile such as a parabolic-shaped refractive-index-distribution can be obtained by measuring the interference fringes. The lens properties of the lead lines connected to each electrode and the improvement of response time will also be described.
