  • Patent number: 10108146
    Abstract: An anisotropic spatial acousto-optic modulator for a holographic display system includes a substrate, an anisotropic waveguide that guides light into a single polarization, and a transducer that generates surface acoustic waves that propagate linearly with the guided, polarized light, converting at least some of the polarized light into a leaky mode of orthogonally polarized light. The acoustic waves may be encoded with holographic information. The modulator may include coupling devices for coupling light into the waveguide, which may have multiple channels. A holographic video display system includes at least one anisotropic spatial acousto-optic modulator. The pattern of the surface acoustic waves, encoded with holographic information, acts as a diffraction pattern that causes the modulator output to form a wavefront that becomes at least part of a holographic image. The system may have multiple channels in multiple waveguides, wherein each waveguide writes one or more lines of the holographic image.

  • Publication number: 20180074457
    Abstract: A holographic display is comprised of space-multiplexed elemental modulators, each of which consists of a surface acoustic wave transducer atop an anisotropic waveguide. Each “line” of the overall display consists of a single anisotropic waveguide across the display's length with multiple surface acoustic wave transducers spaced along the waveguide length, although for larger displays, the waveguide may be divided into segments, each provided with separate illumination. Light that is undiffracted by a specific transducer is available for diffraction by subsequent transducers. Per transducer, guided-mode light is mode-converted to leaky-mode light, which propagates into the substrate away from the viewer before encountering a volume reflection grating and being reflected and steered towards the viewer. The display is transparent and all reflection volume gratings operate in the Bragg regime, thereby creating no dispersion of ambient light.

  • Publication number: 20160223988
    Abstract: A flat-panel holographic video display includes a control layer and waveguide elements. Each waveguide element has a light-guiding substrate and an array of transducers configured to produce a diffraction grating comprising surface acoustic waves. The grating causes the waveguide to outcouple light, focusing it to, or producing wavefront curvatures consistent with it having emanated from, one or more points, in order to form a holographic image. The transducer array may include a large number of densely packed, vertically-adjacent transducers for each hogel for full parallax or may include a small number of vertically-adjacent transducers and a cylindrical optical element for each hogel. A spatial filter may be used to block noise. The display may be edge-illuminated by a collinear multicolor source. The substrate exit face may have nanopatterned areas alternated with flat areas in order to create regions of optimal internal reflection next to regions of low reflection.

  • Publication number: 20140300695
    Abstract: A full-parallax acousto-optic/electro-optic holographic video display includes a control layer and a piezo-electric layer, which includes a substrate and an array of anisotropic waveguide elements. Each waveguide element guides light into a single polarization and includes a horizontal grating, which diffracts light horizontally and comprises surface acoustic waves, and vertical grating, which diffracts light vertically and includes an electro-optic phased array. The surface acoustic waves propagate linearly with the guided, polarized light in the waveguide, converting the polarized light into a leaky mode of orthogonal polarized light. The combination of the horizontal and vertical gratings allows the waveguide element to focus light to multiple points and steer it in order to form a holographic image. The horizontal grating may be generated by interdigital acousto-optic transducers and the vertical grating may be controlled by electro-optic transducers.

  • Patent number: 8505058
    Abstract: A synchronization mechanism embeds synchronization triggers into a television signal or stream at regular intervals. The triggers include an accurate representation of the time in which the triggers were embedded. A receiving device decodes the triggers and synchronizes its internal timer based on the triggers. In this regard, the receiving device obtains a reference time from the internal timer and computes an offset between the reference time and the trigger time. The computed offset is then applied to the reference time. With the receipt of each new trigger, the application compares the trigger time to a new reference time with the most recently computed offset value applied. If there is any variance between these two values, the application creates a new smoothed offset.

  • Patent number: 8356329
    Abstract: A system and method for adding hyperlinked information to a television broadcast in which an interactive content icon is used. The broadcast material is analyzed and one or more regions within a frame are identified. Additional information can be associated with a region, and can be transmitted in encoded form, using timing information to identify the frame with which the information is associated. A receiver displays the annotation information associated with the video signal in response to a viewer request on a frame by frame basis. The interactive content icon can be used to inform a viewer of the presence of hyperlinked information, for teaching the viewer how to use the system, and for informing the viewer about the hyperlinked information.
