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 variable liquid crystal optical device for controlling the propagation of light has one or more transparent thin-film highly-resistive layer (HRL) coupled to a substrate and an electrode structure. The HRL has core layer and a cover or proximity layer, wherein the core layer material has a higher electrical conductivity and higher refractive index than the cover layer material; and wherein the core and cover layer materials have substantially the same free energies of formation of oxide. In this way, the electrode structure will be environmentally stable and responsive to an applied electrical current to generate a spatially non-uniform magnetic field.

Abstract: A wafer level method of manufacturing a liquid crystal optical device removes the need for a rigid barrier fillet while minimizing any risk of contamination of the liquid crystal. An uncured adhesive may be deposited on a bottom substrate and partially cured to form a liquid crystal barrier. After addition of the liquid crystal and a top substrate, the adhesive is fully cured to bond the substrate layers together. An uncured adhesive may be used together with the partially cured adhesive, and may be deposited separately or filled into an extracellular matrix surrounding a plurality of liquid crystal cells. The adhesive may be cured by a variety of means, including light that may be spatially modulated. One or both of the substrates may be deformed during assembly so as to create a structure with a lensing effect on light passing through the liquid crystal region.

Abstract: A controllable light propagation system includes a light guide elongated in a first direction, a controllable liquid crystal (LC) element including an LC material and having a first side adjacent the light guide to define a dynamic interface between the light guide and controllable LC element, and an array of electrodes arranged at different locations along the first direction. The array of electrodes arranged along the first direction are selectively activatable to generate electric fields in the LC material to control a transmissivity of the dynamic interface between the light guide and the controllable LC element, thereby allowing a controlled extraction of light at selected locations along the light guide. An array of optical elements may be provided at a second side of the controllable LC element to deflect or otherwise influence the extracted light, e.g., as a function of the location of the extracted light along the first direction.

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: A variable light beam is provided from a light source. The light source can be an LED light source or other source. The light source includes basic collimation optics, such as reflector or Fresnel lens, an electrically controllable LC device, such as a polydisperse LC film, in front of the incident spot light beam. Preferably the polydisperse LC film includes transparent flat uniform electrode layers. The LC device can be autonomous of the light source. The proposed solution provides a dynamically controllable, preferably polarizer-free and pixel-free, beam shape light source module including a controllable light beam control module and a light source module providing the initial light beam in a scanner light source, a camera flash, an architectural, automobile or industrial lighting device.
