  • Patent number: 10827915
    Abstract: A method of imaging through a medium is disclosed. The method comprises: illuminating the medium by a non-diffracting light beam over a plurality of locations on a boundary of the medium; collecting back scattered light for each location of the light beam; and constructing an image based on intensity levels of the back scattered light at each of the plurality of locations, the intensity levels constituting local contrasts over the image.
    Type: Grant
    Filed: August 7, 2017
    Date of Patent: November 10, 2020
    Assignee: Ramot at Tel-Aviv University Ltd.

  • Patent number: 8502132
    Abstract: A method for manipulating a plurality of objects. The method includes the steps of providing a shaping source, applying the shaping source to create a spatially symmetric potential energy landscape, applying the potential energy landscape to a plurality of objects, thereby trapping at least a portion of the plurality of objects in the,24 potential energy landscape, spatially moving the potential energy landscape to manipulate the plurality of objects; and extinguishing the potential energy landscape, thereby causing the plurality of objects to move freely when the potential energy landscape is extinguished.

  • Patent number: 8394708
    Abstract: A method and system for assembling a quasicrystalline heterostructure. A plurality of particles is provided with desirable predetermined character. The particles are suspended in a medium, and holographic optical traps are used to position the particles in a way to achieve an arrangement which provides a desired property.

  • Patent number: 8174742
    Abstract: A system and method for creating extended optical traps for applying optical forces to a material to be manipulated for a commercial application. The system and method include applying a hologram of appropriate characteristics to a beam of light wherein the hologram characteristics include a transverse optical component to apply optical forces transverse to an optical axis of the system. A shape phase component achieves this transverse optical component and also intensity gradient components can be applied via the hologram to provide programmable extended optical traps for a selectable commercial application.

  • Patent number: 7973275
    Abstract: Holographic optical traps using the forces exerted by computer-generated holograms to trap, move and otherwise transform mesoscopically textured materials. The efficacy of the present invention is based upon the quality and nature of the diffractive optical element used to create the traps and dynamically use them. Further a landscape of potential energy sites can be created and used to manipulate, sort and process objects.

  • Patent number: 7772543
    Abstract: A system and method for manipulating and processing nanowires in solution with arrays of holographic optical traps. The system and method of the present invention is capable of creating hundreds of individually controlled optical traps with the ability to manipulate objects in three dimensions. Individual nanowires with cross-sections as small as 20 nm and lengths exceeding 20 ?m are capable of being isolated, translated, rotated and deposited onto a substrate with holographic optical trap arrays under conditions where single traps have no discernible influence. Spatially localized photothermal and photochemical processes induced by the well-focused traps can also be used to melt localized domains on individual nanowires and to fuse nanowire junctions.
