Publication number: 20240126073Abstract: In a range imaging system, a passive optical system has a set of lenses and an optical mask that varies a point spread function of the set of lenses so as to encode in an optical field arriving from a scene range information for objects in the scene that are at least X meters from the mask, where X is at least 10. A digital light sensor receives the optical field, and an image processor processes signals receive signals from the sensor to decode the range information.Type: ApplicationFiled: October 4, 2023Publication date: April 18, 2024Applicant: Technion Research & Development Foundation LimitedInventors: Yoav SHECHTMAN, Nadav OPATOVSKI

Patent number: 10638112Abstract: Various embodiments include an apparatus including a phase mask and circuitry. The phase mask is configured and arranged with optics in an optical path to modify a shape of light, passed from an object. The shape modification characterizes the light as having two lobes with a lateral distance that changes along a line, having a first orientation, as a function of an axial proximity of the object to a focal plane, and with the line having a different orientation depending on whether the object is above or below the focal plane. The circuitry is configured and arranged to generate a three-dimensional image from light detected at the image plane, by using the modified shape to provide depth-based characteristics of the object.Type: GrantFiled: January 17, 2019Date of Patent: April 28, 2020Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Yoav Shechtman, William E.
