    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: A liquid crystal optical device providing refractive Fresnel lens type element control over light passing through an aperture is provided. The device includes a layer of liquid crystal material contained by flat substrates having flat alignment layers; and an arrangement of electrodes configured to provide a spatially varying voltage distribution within a number of lensing zones within said liquid crystal layer. The arrangement of electrodes includes ring-shaped electrodes defining boundaries between Fresnel lensing zones. The liquid crystal optical device is structured to provide a spatial variation in the optical phase delay with an abrupt transition at a boundary between lensing zones to increase the effective aperture of the optical device.

    Abstract: An intraocular adaptive lens prosthesis apparatus is provided. In some implementations the apparatus includes a tunable liquid crystal lens encapsulated in the intraocular prosthesis with control electronics and a power source. In other implementations the apparatus includes a tunable liquid crystal lens encapsulated in the intraocular prosthesis with a control signal receiver while an external control electronics package transmits the control signal. The tunable liquid crystal lens is driven in response to a stimulus signal to provide accommodation. In some embodiments the tunable liquid crystal device corrects other visual shortcomings of the natural eye.

    Abstract: A motionless adaptive focus stereoscopic scene capture apparatus employing tuneable liquid crystal lenses is provided. The apparatus includes at least two image sensors preferably fabricated as a monolithic stereo image capture component and at least two corresponding tuneable liquid crystal lenses preferably fabricated as a monolithic focus adjustment component. Using a variable focus tuneable liquid crystal lens at each aperture stop provides constant magnification focus control. Controlled spatial variance of a spatially variant electric field applied to the liquid crystal of each tuneable liquid crystal lens provides optical axis shift enabling registration between stereo images. A controller implements coupled auto-focusing methods employing multiple focus scores derived from at least two camera image sensors and providing multiple tuneable liquid crystal lens drive signals for synchronous focus acquisition of a three dimensional scene. Wafer manufacture provides a compact stereoscopic image capture apparatus for endoscopic surgery, optical inspection and entertainment applications.
