  • Patent number: 10288904
    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. An array of excitation electrodes, including parallel conductive stripes extending over the active area is disposed over one or both sides of the electro-optical layer. Control circuitry is coupled to apply respective control voltage waveforms to the excitation electrodes and is configured to concurrently modify the respective control voltage waveforms applied to excitation electrodes so as to generate a specified phase modulation profile in the electro-optical layer.

  • Patent number: 9025073
    Abstract: Imaging apparatus includes an image sensor, which is adapted to generate an input image in response to optical radiation. A processing engine is configured to apply a digital filter, having a kernel width greater than five pixels, to the input image to generate a filtered image. An optical assembly is arranged to focus the optical radiation onto the image sensor with a point spread function such that no more than a first threshold percentage of energy emitted from a point object and focused by the optical assembly falls within a first region of the image sensor having a first width five times the pitch of the image sensor, while at least a second threshold percentage of the energy emitted from the point object and focused by the optical assembly falls within a second region, which contains the first region and has a second width corresponding to the kernel width.
