Outline of Final Research Achievements |
There exists a trade-off problem between a lens power and a response time for changing a focal length of a liquid crystal (LC) lens. As a result of this study, it became possible to change a focal length of the LC lens rapidly based on our proposed effective voltage control without any loss of its lens power. This is advantageous of producing a LC wide-angle fovea lens with a smaller size, larger energy conservation, and higher optical performance.
