Patent number: 9386299Abstract: A method including providing a device that projects a pattern of coherent radiation. The method further includes capturing a reference image of the pattern using an image sensor by projecting the pattern of the coherent radiation onto a reference surface and engendering a relative motion between the reference surface and the image sensor while capturing the reference image. The method also includes storing the reference image in a memory associated with the device.Type: GrantFiled: June 11, 2014Date of Patent: July 5, 2016Assignee: APPLE INC.Inventors: Alexander Shpunt, Dmitri Rais, Niv Galezer

Patent number: 9330324Abstract: A method for forming a three-dimensional (3D) map of an object, including illuminating the object from a light source so as to project a pattern onto the object, capturing an image of the pattern using an array of detector elements, and processing the captured image so as to measure respective offsets of elements of the pattern in the captured image relative to a reference pattern, the offsets including at least a first offset of a first element of the pattern and a second offset of a second element of the pattern, measured respectively in first and second, mutually-perpendicular directions in a plane of the array. The method further includes computing a correction factor in response to the first offset, applying the correction factor to the second offset so as to find a corrected offset, and computing depth coordinates of the object in response to the corrected offset.Type: GrantFiled: July 5, 2012Date of Patent: May 3, 2016Assignee: APPLE INC.Inventors: Daniel Cohen, Dmitri Rais, Erez Sali, Niv Galezer, Alexander Shpunt

Patent number: 8829406Abstract: Optical apparatus includes a device package, with a radiation source contained in the package and configured to emit a beam of coherent radiation. A diffractive optical element (DOE) is mounted in the package so as to receive and diffract the radiation from the radiation source into a predefined pattern comprising multiple diffraction orders. An optical detector is positioned in the package so as to receive and sense an intensity of a selected diffraction order of the DOE.Type: GrantFiled: July 8, 2013Date of Patent: September 9, 2014Assignee: Primesense Ltd.Inventors: Ronen Akerman, Dudu Voschina, Niv Galezer, Yoed Arieli, Tomer Segev, Zafrir Mor, Alexander Shpunt
