Patent number: 9176054Abstract: The present invention provides an apparatus for tomographic imaging of an object. The apparatus includes a light unit configured to generate illumination, which comprises coherent light and has random phase distribution in a plane perpendicular to an optical axis, for illuminating an object, a coupler which combines a reference beam and an object beam for an interference, a shifter configured to shift relative phase difference between the object light and the reference coherent light, a detector configured to detect an interference caused by the reference coherent light and object light for the each phase, and a processor configured to calculate an optical propagation based on the detected interference for the each phase.Type: GrantFiled: June 7, 2012Date of Patent: November 3, 2015Assignees: Canon Kabushiki Kaisha, THE ARIZONA BOARD OF REGENTSInventors: Isao Matsubara, Chung-Chieh Yu, William Dallas

Patent number: 9116303Abstract: The present invention provides a hologram which forms a light intensity distribution on a predetermined plane by using incident light. The hologram includes a plurality of cells configured to control both a phase of a first polarized light component in a first polarization direction of the incident light and a phase of a second polarized light component in a second polarization direction perpendicular to the first polarization direction, to form a phase difference distribution between phase distributions for the first and second polarized light components. The plurality of cells are designed so that a number of phase difference levels of the phase difference distribution is less than a number of phase levels of the phase distribution of the first polarized light component.Type: GrantFiled: March 5, 2010Date of Patent: August 25, 2015Assignees: CANON KABUSHIKI KAISHA, ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Isao Matsubara, Yasuyuki Unno, William Dallas, Tom D Milster

Patent number: 8588455Abstract: An earphone wire cover with three separate arms resembling drinking straws joined together in a Y-configuration into which the ear phone speakers and plug are inserted and passed through. These covers enclose most of the wire from the electronic device to the earphones. The three sections are joined together with a flexible tape or string so that, when the earphones are to be stored, the three arms can be brought together as three parallel tubes holding the bulk of the wire by simply flipping the bottom section into alignment with the upper two sections. The invention can be easily re-deployed by simply folding the bottom section out again and separating the top ends to make a Y. An alternate embodiment of the invention can have a microphone hole in one of the arms.Type: GrantFiled: March 8, 2011Date of Patent: November 19, 2013Inventor: William Dallas

Patent number: 8531747Abstract: The present invention provides a hologram which forms a light intensity distribution on a predetermined plane by using an incident light. The hologram includes a plurality of cells configured to control both a phase of a first polarized light component of the incident light and a phase of a second polarized light component. The plurality of cells are designed to form a portion in an overlap region in which a first light intensity distribution region formed on the predetermined plane by the first polarized light component and a second light intensity distribution region formed on the predetermined plane by the second polarized light component are superposed on each other. The phase of the first polarized light component is diffused in the portion formed in the overlap region.Type: GrantFiled: June 24, 2009Date of Patent: September 10, 2013Assignee: Canon Kabushiki KaishaInventors: Isao Matsubara, Yasuyuki Unno, William Dallas
