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: Los aparatos de cristal líquidos variables para controlar la propagación de la luz a través de una capa de cristal líquido utilizan un material dependiente de la frecuencia para reconfigurar dinámicamente las estructuras efectivas de los electrodos en el aparato. La frecuencia de una señal de operación que genera un campo eléctrico en el aparato puede ser variada, y el material dependiente de la frecuencia tiene diferentes movilidades de carga para las diferentes frecuencias. En una movilidad de baja carga, el material dependiente de la frecuencia tiene poco efecto en la estructura existente del electrodo. Sin embargo, en una movilidad de alta carga, el material dependiente de la frecuencia aparece como una extensión de los electrodos fijos, y puede ser utilizada para cambiar la estructura efectiva del electrodo y de esta manera, el perfil espacial del campo eléctrico. Este, a la vez, cambia las propiedades ópticas del cristal líquido, permitiendo de esta manera que el aparato óptico sea controlable por la frecuencia.

Abstract: A lighting device using a liquid crystal beam modulator produces good broadening of a light beam. The liquid crystal cell has a patterned electrode structure having a pattern of paired electrodes on a first one of a pair of cell substrates for providing a spatially modulated electric field extending into a liquid crystal material, and the cell is arranged with respect to a light source so that an incident beam will arrive through another of the pair of substrates and exit from the first one of the pair of substrates.
