| Outline of Final Research Achievements |
Multi-electrode structure of the Liquid Crystal Wide Angle Fovea Lens has been proposed in order to move the attention point inside its field of view without mechanical parts. By using this multi-electrode structure, the designed local zoom unit achieves focused imaging when multiple attention points are given simultaneously. The virtual lens composed of a single lens with two aspherical surfaces has been defined as the physical lens shape model corresponding to a pair of the liquid lens cell to solve a problem where lens focus is deteriorated in a part of the field of view. Using this model, it is calculated how much optical refraction and corresponding physical shape are required to the lens in order to achieve a target magnification. Based on this concrete physical lens shape, we can determine required liquid crystal material, electrode size and thickness of the liquid crystal layer of the liquid crystal lens cell.
