摘要： The liquid crystal lens of the invention has an optically transparent liquid crystal plate which includes a plurality of liquid crystal pixels divided two-dimensionally, and a liquid crystal drive section which selects only a part of the liquid crystal pixels simultaneously and controls voltage application to the selected liquid crystal pixels. The liquid crystal drive section performs voltage application control to the selected liquid crystal pixels so as to form, in the liquid crystal plate, a refractive index distribution of light which transmits the liquid crystal plate.

摘要： An optical device and a lens unit each include a liquid container containing an insulating liquid and an electroconductive liquid which are mutually immiscible and optically transparent and have different refractive indices. The optical device and the lens unit also have a gas-absorbing material in or around the liquid container. The gas-absorbing material absorbs gas generated by energization. The optical device and the lens unit can maintain their optical characteristics even if voltage is repeatedly applied. An imaging apparatus includes an optical shooting system having the optical device. The imaging apparatus takes pictures by capturing object light coming through the optical shooting system.
