Abstract: A lidar system may include a programmable configuration memory, configured to receive configuration values for controlling histogramming operations performed by the lidar system. The lidar system may also include an array controller, configured or programmed or set to read the configuration values and send control signals according to the configuration values in the programmable configuration memory. The lidar system may also include a sensor array, where the sensor array includes a plurality of pixels. Each pixel in the plurality of pixels may include a photosensor, summation circuitry, and a memory device. Each of the plurality of pixels may be configured to generate histogram data by collecting photon counts during a plurality of time bins for each of a plurality of laser cycles.
