1. A method comprising:
measuring a first set of photon-event data collected from a first crosstalk-monitoring zone of an optical receiver during a first period of time of flight ranging;
measuring a second set of photon-event data collected from a second crosstalk-monitoring zone of the optical receiver during the first period of time of flight ranging; and
generating a first dynamic crosstalk compensation value for a first histogram region of the optical receiver using the first set of photon-event data, the second set of photon-event data, and a native crosstalk compensation value for the first histogram region of the optical receiver.
