Abstract: Embodiments of a system and method are disclosed. In an embodiment, a LiDAR (Light Detection and Ranging) system that can include a sensor circuit comprising a controller unit, a transmitter, a gating circuit, and a receiver element, wherein the gating circuit is connected to the controller unit and to the receiver element, wherein signals detected by the sensor circuit correspond to at least one physical object located in an operating region with respect to a location of the sensor circuit and based on multiple measurements. The gating circuit can range-gate the receiver element based on a range-gating waveform, and the controller unit can provide a phase-delay parameter for phase shifting the range-gating waveform with different phase values relative to a light signal transmitted by the transmitter for different measurements by the sensor circuit.

Abstract: The disclosure relates to time of flight calculations for a lidar transceiver. Example embodiments include a method of calculating time of flight of a lidar signal, the method comprising: i) transmitting a light pulse to start (502) an acquisition time period having a plurality of successive time portions; ii) for each successive time portion, if a photon is received (503): iia) recording (505) a time at which the photon is received; iib) updating (504) a histogram to record a cumulative count of photons received during the time portion; iic) calculating (505) a time difference between the time at which the photon is received relative to a reference point of the time portion; iid) updating (506) a cumulative total of the calculated time difference for the time portion; iii) repeating steps i) to iid) for a succession of N transmitted light pulses; iv) identifying (509) a peak in a time portion of the histogram; and v) estimating (510) a time of flight from the cumulative total of the calculated time difference for the time portion of the histogram containing the identified peak.

Abstract: Various example embodiments are directed to apparatuses and methods including an apparatus having sensor circuitry and processing circuitry. In one example, sensor circuitry produces and senses detected signals corresponding to physical objects located in an operational region relative to a location of the sensor circuitry. The processing circuitry records and organizes information associated with the detected signals in a plurality of sub-histograms respectively associated with different accuracy metrics for corresponding sub-regions of the operational region, each of the plurality of sub-histograms including a set of histogram bins characterized by a bin width linked to its accuracy metric, and refines at least one of the accuracy metric by adapting one or more of the bin widths dynamically in response to the detected signals.

Abstract: An apparatus includes a printed circuit board (PCB), a solder pad, a signal via, a plurality of metalized vias, and a waveguide. The PCB has a first surface opposite a second surface and includes a first metal layer, a second metal layer having a waveguide opening, and a PCB channel region from the waveguide opening in the second metal layer to the second surface. The solder pad is positioned on the first surface of the PCB over the channel region, and the signal via is coupled to the solder pad and a via pad in the second metal layer within the waveguide opening. The plurality of metalized vias extend from the first surface to the second surface of the PCB and form a boundary around the channel region. The waveguide is affixed to the waveguide opening in the second metal layer.
