摘要： A liquid crystal optical device providing refractive Fresnel lens type element control over light passing through an aperture is provided. The device includes a layer of liquid crystal material contained by flat substrates having flat alignment layers; and an arrangement of electrodes configured to provide a spatially varying voltage distribution within a number of lensing zones within said liquid crystal layer. The arrangement of electrodes includes ring-shaped electrodes defining boundaries between Fresnel lensing zones. The liquid crystal optical device is structured to provide a spatial variation in the optical phase delay with an abrupt transition at a boundary between lensing zones to increase the effective aperture of the optical device.

摘要： A spatially non-uniform electrode structure is proposed for controlling a spatially non-uniform electric field driving a tunable liquid crystal lens. The spatially non-uniform electrode structure enables the generation of a predetermined spatially non-uniform electric field profile where complex capacitive coupling between multiple different electrically floating neighboring electrode segments is employed for the generation of the electrical field of desired form by supplying an initial electric potential to a limited number of electrodes.

摘要： A tunable liquid crystal optical device defining an optical aperture and having a layered structure. The device includes a film electrode formed on a surface of a first substrate and covered by a second substrate, and a contact structure filling a volume within the layered structure and contacting the film electrode. The contact structure is located outside of the optical aperture and provides an electrical connection surface much larger than a thickness of the film electrode, such that reliable electrical connections may be made to the electrode, particularly in the context of wafer scale manufacturing of such a device.
