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.
