Publication number: 20230333217Abstract: A method for optical sensing includes directing a series of optical pulses toward a target scene and imaging optical radiation that is reflected from the target scene onto an array of single-photon detectors, which output electrical pulses in response to photons that are incident thereon. The electrical pulses output by the single photon detectors are counted in multiple different gating intervals that are synchronized with each of the optical pulses, including at least first and second gating intervals at different, respective delays relative to the optical pulses, while the delays are swept over a sequence of different delay times during the series of the optical pulses. A time of flight of the optical pulses is computed by comparing respective first and second counts of the electrical pulses that were accumulated in the first and second gating intervals over the series of the optical pulses.Type: ApplicationFiled: June 19, 2023Publication date: October 19, 2023Inventors: Nadav Fine, Amir Nevet, Oz Barak

Patent number: 11733359Abstract: Optical sensing apparatus includes at least one semiconductor substrate and a first array of single-photon detectors, which are disposed on the at least one semiconductor substrate, and second array of counters, which are disposed on the at least one semiconductor substrate and are configured to count electrical pulses output by the single-photon detectors. Routing and aggregation logic is configured, in response to a control signal, to connect the single-photon detectors to the counters in a first mode in which each of at least some of the counters aggregates and counts the electrical pulses output by a respective first group of one or more of the single-photon detectors, and in a second mode in which each of the at least some of the counters aggregates and counts the electrical pulses output by a respective second group of two or more of the single-photon detectors.Type: GrantFiled: October 26, 2020Date of Patent: August 22, 2023Assignee: APPLE INC.Inventors: Nadav Fine, Amir Nevet, Oz Barak

Patent number: 11555900Abstract: Depth-sensing apparatus includes a laser, which emits pulses of optical radiation toward a scene. One or more detectors receive the optical radiation that is reflected from points in the scene and to output signals indicative of respective times of arrival of the received radiation. A scanner scans the pulses of optical radiation across the scene along successive parallel scan lines of a raster. Control and processing circuitry drives the laser to emit a succession of output sequences of the pulses with different, respective temporal spacings between the pulses within the output sequences in the succession, and matches the times of arrival of the signals due to the optical radiation reflected from the points in at least two adjacent scan lines in the raster to the temporal spacings of the output sequences in order to find respective times of flight for the points in the scene.Type: GrantFiled: November 11, 2019Date of Patent: January 17, 2023Assignee: APPLE INC.Inventors: Oz Barak, James J. Reuther, Malcolm J. Northcott, Nadav Fine

Publication number: 20220244391Abstract: Optical sensing apparatus includes a radiation source, which directs a series of optical pulses toward a target scene. A first array of single-photon detectors receives optical radiation that is reflected from the target scene and outputs electrical pulses in response to incident photons. A second array of counters aggregates and counts the electrical pulses output by the single-photon detectors over respective periods indicated by respective gating signals applied to the counters. Control logic applies the respective gating signals to the counters, in each of a sequence of image frames, so as to cause different ones of the counters to aggregate and count the electrical pulses output by one or more of the single-photon detectors over different, respective gating intervals relative to each of the optical pulses, and to sum the frame histograms generated with different temporal offsets so as to compute and output a cumulative histogram.Type: ApplicationFiled: December 12, 2021Publication date: August 4, 2022Inventors: Shingo Mandai, Cristiano L Niclass, Nadav Fine, Oz Barak, Rahmi Hezar

Patent number: 10491431Abstract: In the subject system, a receiver includes a feed forward circuit, a phase recovery circuit, and a feedback circuit. The feed forward circuit compensates for near reflections and provides an input to the phase recovery circuit and the feedback circuit. The phase recovery circuit performs phase recovery and provides phase recovery information to the feedback circuit. The feedback circuit adjusts and/or corrects a received symbol based at least in part on the received phase recovery information.Type: GrantFiled: September 28, 2018Date of Patent: November 26, 2019Assignee: Maxlinear Asia Singapore PTE LTDInventors: Nadav Fine, Evgeny Levitan, Eran Ridel, Ran Soffer, Uri Kanari, Nati Mizrahi

Patent number: 10419132Abstract: The continuous demand for capacity and the limited available spectrum in wireless and wired communication has led to reliance on advanced modulation techniques to dramatically increase the number of bits per hertz per second. This demand in capacity and using the higher order constellations shorten the link range, and as a result, system gain becomes an important characteristic. The modulation techniques described here improve the system gain by, e.g., as much as 2.5 dB in high order modulations such as 4096-QAM. The modulation techniques include reducing the peak to average ratio and adding shaping gain. These techniques dramatically improve the system capacity, system gain, power consumption and system cost.Type: GrantFiled: January 23, 2019Date of Patent: September 17, 2019Assignee: Maxlinear Asia Singapore PTE LTDInventors: Nadav Fine, Ran Soffer
