  • Patent number: 12181750
    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.

  • Patent number: 11953764
    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.

  • Patent number: 11927771
    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.

  • Publication number: 20220214566
    Abstract: Apparatus for vision correction includes an electrically-tunable optical phase modulator (42, 44), which is configured to be mounted in proximity to an eye of a subject. Control circuitry (26) is configured to apply drive signals to the optical phase modulator so as to generate in the optical phase modulator a first phase modulation profile in a central zone (37) that intercepts a line of sight (32) of the eye and a second phase modulation profile, different from the first phase modulation profile, in a peripheral zone (39) extending peripherally around the central zone over at least 180° of arc. The first phase modulation profile is selected so as to enable clear vision by the eye in the central zone, while the second phase modulation profile is selected so as to blur light that is incident on the eye through the peripheral zone.
