Abstract: An optical device includes an electro-optical layer, having an effective local index of refraction at any given location within an active area of the electro-optical layer that is determined by a voltage waveform applied across the electro-optical layer at the location. Conductive electrodes extend over the first and second sides of the electro-optical layer. The conductive electrodes include an array of excitation electrodes including parallel stripes of a transparent conductive material having gaps between the stripes of a gap width that is less than the layer thickness of the electro-optical layer. Control circuitry is coupled to apply respective control voltage waveforms to the excitation electrodes and to modify the control voltage waveforms applied to each of the excitation electrodes concurrently and independently so as to generate a phase modulation profile in the electro-optical layer.

Abstract: An augmented reality system (70, 100, 140, 180, 190) includes an augmented reality projector (72, 102, 142, 192) that is configured to project an image to an eye (82, 118, 154, 206) of an observer and to allow the observer to view a real scene (80, 116, 164, 204) through the projector. The system further includes first and second electrically-tunable dynamic lenses (74, 76, 104, 106, 144, 146, 194, 196), which are positioned respectively on opposing first and second sides of the projector, and a controller (78, 110, 150, 198) that is coupled to the projector and the first and second electrically-tunable dynamic lenses. The controller is configured to receive an adjustable accommodation parameter and a specified distance of interest and to set respective first and second refractive powers of the first and second dynamic lenses responsively to the adjustable accommodation parameter and the distance.

Abstract: An optical device (20) includes an electro-optical layer, including a liquid crystal material (24) with a heliconical structure having a pitch that is less than 250 nm and is modifiable by an electric field. An array of excitation electrodes (28) extends over the electro-optical layer. Control circuitry (23) is coupled to apply control voltage waveforms to the excitation electrodes and is configured to modify the control voltage waveforms so as to locally modify a molecule director angle of the heliconical structure and thus to generate a specified phase modulation profile in the electro-optical layer.

Abstract: Optical apparatus (38) includes an electro-optical layer (46), contained within a transparent envelope (43, 44) and having an effective local index of refraction at any given location that is determined by a voltage waveform applied across the electro-optical layer at the location. An array of excitation electrodes (50) is disposed over a surface of the transparent envelope. Control circuitry (42) is configured to apply voltage waveforms to the excitation electrodes so as to generate across at least a part of the active area of the electro-optical layer a phase modulation profile (60, 63, 64, 65, 66, 67, 70) comprising spatially alternating peaks (61) and troughs (62) separated by phase transitions chosen so as to emulate a Fresnel lens. The troughs have respective phase modulation depths that vary by at least one quarter wavelength at a nominal wavelength of 500 nm across at least the part of the active area of the electro-optical layer that emulates the Fresnel lens.

Abstract: Optical apparatus includes an electrically-tunable lens, including an electro-optical layer, having, for a given polarization of light incident on the layer, an effective local index of refraction at any given location within an active area of the electro-optical layer that is determined by a voltage waveform applied across the electro-optical layer at the location. Conductive electrodes extend over opposing first and second sides of the electro-optical layer and include an array of excitation electrodes. Control circuitry applies control voltage waveforms to the excitation electrodes. A polarization rotator is positioned and configured to intercept incoming light that is directed toward the lens and to rotate a polarization of the intercepted light so as to ensure that the light incident on the electro-optical layer has a component of the given polarization regardless of an initial linear polarization of the intercepted light.
