    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.

    Abstract: A liquid crystal optical device is described configured to provide variable beam steering or refractive Fresnel lens control over light passing through an aperture of the device. The device includes at least one layer of liquid crystal material contained by substrates having alignment layers. An arrangement of electrodes is configured to provide a spatially varying electric field distribution within a number of zones within the liquid crystal layer. The liquid crystal optical device is structured to provide a spatial variation in optical phase delay with a transition at a boundary between zones which is an approximation of a sawtooth waveform across the boundaries of multiple zones. The arrangement of electrodes, device layered geometry and methods of driving the electrodes increase the effective aperture of the overall optical device.

    Abstract: A reprogrammable intraocular adaptive lens prosthesis apparatus is provided. The apparatus includes a tunable liquid crystal lens (TLCL) encapsulated in the intraocular prosthesis with control electronics and a power source or in the intraocular prosthesis with a control signal receiver while an external control electronics package transmits the control signal. The TLCL is driven in response to a stimulus signal to provide accommodation. The TLCL corrects other visual shortcomings of the natural eye. The intraocular prosthesis has a remote programmable TLCL controller configured to recalibrate the TLCL to compensate for dynamic adaptation of the eye over time.

    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: An architectural lighting device for wall washing providing suitable beam modulation is described herein. The device combines a variable divergence beam source (a light source along with a beam stretching element) in combination with a specially designed side reflector that redirects a portion of a broadened beam back onto the wall so as to have wall illumination increase with beam divergence.
