Abstract: Abstract A liquid crystal optical device is provided. The optical device includes a liquid crystal cell controlling optical properties of light passing there through and has: a liquid crystal layer, a planar electrode located to one side of said liquid crystal layer; an electric field control structure located to the opposite side of the liquid crystal layer; and a wavefront adjustment structure configured to provide optical phase front adjustment. In some embodiments the wavefront adjustment structure is a conductive floating electrode. In other embodiments the wavefront adjustment structure is a weakly conductive layer (WCL) having spatially variable sheet resistance. In other embodiments the wavefront adjustment structure is a weakly conductive structure having spatially variable sheet resistance with a frequency dependent characteristic.

Abstract: Variable liquid crystal devices for controlling the propagation of light through a liquid crystal layer use a frequency dependent material to dynamically reconfigure effective electrode structures in the device. The frequency of a drive signal that generates an electric field in the device may be varied, and the frequency dependent material has different charge mobilities for the different frequencies. At a low charge mobility, the frequency dependent material has little effect on the existing electrode structures. However, at a high charge mobility, the frequency dependent material appears as an extension of the fixed electrodes, and may be used to change the effective electrode structure and, thereby, the spatial profile of the electric field. This, in turn, changes the optical properties of the liquid crystal, thus allowing the optical device to be frequency controllable.

Abstract: A liquid crystal lens or beam steering device is made by programming alignment surfaces of the LC cell walls using a programming field to align the alignment surface molecules before fixing them. By setting the desired pre-tilt, the lens can operate in the absence of the control field, and power consumption by the control field can be reduced.

Abstract: Eine variable Flüssigkristall-Optikvorrichtung zum Steuern der Ausbreitung von Licht weist eine oder mehrere transparente Dünnfilm-hochohmige Schicht (HRL) auf, die mit einem Substrat und einer Elektrodenstruktur gekoppelt ist. Die HRL weist eine Kernschicht und eine Deck- oder Näherungsschicht auf, wobei das Kernschichtmaterial eine höhere elektrische Leitfähigkeit und einen höheren Brechungsindex als das Deckschichtmaterial aufweist; Und wobei die Kern- und Deckschichtmaterialien im Wesentlichen die gleichen freien Energien der Oxidbildung aufweisen. Auf diese Weise wird die Elektrodenstruktur umweltstabil und reagiert auf einen angelegten elektrischen Strom, um ein räumlich ungleichförmiges Magnetfeld zu erzeugen.
