Patents by Inventor Yohai Roichman

Yohai Roichman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8922857
    Abstract: Optical solenoid beams, diffractionless solutions of the Helmholtz equation whose diffraction -limited in-plane intensity peak spirals around the optical axis, and whose wavefronts carry an independent helical pitch. The solenoid beams have the noteworthy property of being able to exert forces on illuminated objects that are directed opposite to the direction of the light's propagation. Optical solenoid beams therefore act as true tractor beams that are capable of transporting material back toward their source.
    Type: Grant

  • Patent number: 8472094
    Abstract: A method and system for manipulating object using a three dimensional optical trap configuration. By use of selected hologram on optical strap can be configured as a preselected three dimensional configuration for a variety of complex uses. The system can include various optical train components, such as partially transmissive mirrors and Keplerian telescope components to provide advantageously three dimensional optical traps.

  • Patent number: 8179577
    Abstract: A method and system for preparing and using three dimensional optical ring traps. The method and system includes applying a single phase hologram to be able to independently control shape and force profile of an optical trap but without employing orbital angular momentum for the control parameter of an optical ring trap to manipulate an object.

  • 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: 7897910
    Abstract: A method and system for establishing extended optical traps for commercial use. The method and system employs a diffractive optical element (DOE) to process a light beam wherein the DOE includes phase information and amplitude information to create the extended optical trap. Such extended traps can be line traps and can be further expanded to two and three dimensional configurations.
