IPC: G02F1/29

Abstract: 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.

Abstract: An electrode structure is proposed for controlling a spatially non-uniform electric field driving a tunable liquid crystal lens or beam steering device. 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.

Abstract: A liquid crystal optical device is provided, including a layered structure including at least two support substrates. An external hole patterned control electrode is provided on one of the substrates and has an aperture. An internal hole patterned control electrode is provided on one of the substrates within the aperture, the internal and outer control electrodes being separated by a gap, which forms part of the aperture. A weakly conductive material is provided on one of the substrates over the aperture. A planar transparent electrode is provided on another one of the substrates. An alignment surface is provided on the substrates over the electrodes. A layer of liquid crystal material is contained by the substrates and in contact with the alignment surface of the substrates. A floating transparent electrode is provided on a side of one of the substrates opposite the outer and the internal hole patterned electrode.
