Patent number: 10827915Abstract: 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: GrantFiled: August 7, 2017Date of Patent: November 10, 2020Assignee: Ramot at Tel-Aviv University Ltd.Inventors: Yael Roichman, Elad Dekel, Dror Kasimov, Harel Nagar, Tsafrir Kolatt

Patent number: 8502132Abstract: 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.Type: GrantFiled: June 14, 2011Date of Patent: August 6, 2013Assignee: New York UniversityInventors: David G. Grier, Marco Polin, Sang-Hyuk Lee, Yael Roichman, Kosta Ladavac

Patent number: 8174742Abstract: 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.Type: GrantFiled: March 14, 2008Date of Patent: May 8, 2012Assignee: New York UniversityInventors: Yohai Roichman, Bo Sun, Yael Roichman, Jesse Amato-Grill, David G. Grier

Patent number: 7973275Abstract: 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.Type: GrantFiled: December 23, 2008Date of Patent: July 5, 2011Assignee: New York UniversityInventors: David G.

Patent number: 7772543Abstract: 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.Type: GrantFiled: January 11, 2006Date of Patent: August 10, 2010Assignees: New York University, Harvard UniversityInventors: David G. Grier, Ritesh Agarwal, Guihua Yu, Charles M. Lieber, Kosta Ladavac, Yael Roichman
