Abstract: An optical object detection device and method using a light emitter and a detector sensitive to reflected light from an object is described herein. The object detection device includes a liquid crystal beam shaping element to allow beam steering, broadening and diffraction of the light emitter. The detection of the object may be done through analyzing the reflected light from different degrees of broadening of the light emitter's beam. The localization and/or the shape of the object may further be determined by analyzing the reflected light from a grid pattern obtained through diffracting the light emitter's beam.

Abstract: For vehicles having left and right headlights, a steering direction signal input indicative of a left or right steering direction is used to modulate a control signal of a liquid crystal beam broadening device to broaden horizontally the vehicle headlight beam when the steering direction signal input is indicative of a selected one of a left or a right steering direction and to maintain or reduce a horizontal spread of the vehicle headlight beam when said steering direction signal input is indicative of one of a left or a right steering direction opposite to the selected steering direction.

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 liquid crystal optical device is provided including at least two LC cells. A first LC cell layer has a predominant director orientation imparting a transversally non-uniform phase delay to a first polarization of an unpolarized incident light field passing therethrough while incident light of a second polarization orthogonal to the first light polarization passes therethrough undergoing transversally uniform phase delay. The first LC cell is configured to project a center extraordinary ray onto an optical axis of the device at the image surface. A second LC cell layer has a predominant director oriented orthogonally to the other predominant director in a plane perpendicular to the optical axis. The second LC layer imparts a transversally non-uniform phase delay to the second polarization of the incident light passing therethrough, the second LC cell being configured to project a center ordinary ray onto the optical axis at the image surface.

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 can 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 can 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 apparatus for controlling light transmission from an optical input to an optical output can function as a tunable iris or eclipse, or as a privacy window. The iris/eclipse can use a liquid crystal matrix with a dispersion of dichroic particles that absorb light in one orientation and transmit light in another, such that controlling the liquid crystal with an electric field allows control of the dichroic particles. Alternatively, a layer may be used with a light absorbing liquid or powder material that moves with a charged material in response to a variable electric field applied to the layer. Privacy windows use a plurality of liquid crystal microlenses that can be controlled with an electric field to allow an image of an optical input to be obtainable at an optical output when in a first state, or to render the image irretrievable when in a second state.

Abstract: Liquid crystal (LC) beam control devices using a dispersion shaped (DS) half wave plate (HWP), with specific physical characteristics, allows the broadened beam to maintain significantly better the color cohesion. Beneficial aspects of using a HWP with an appropriate thickness and birefringence index which makes it inefficient in the blue wavelength spectrum, therefore reducing the blue photon depletion in the center of the broadened beam is described herein. Combinations of an homeotropic LC cell and DS HWP structures for reduced color separation, faster relaxation time and reduced ground state scattering is further described herein.
