Abstract: The present disclosure relates to a method and system for time-of-flight detection. There may be two or more photodetectors in a photodetector circuit that capture photon activity. There is logic that processes the responses of the photodetectors and returns the leading edge of the arrival of the first photon and the leading edge of the arrival of the last photon, if at least two photons are received during an overlapping pulse width.
