Abstract

A course of a signal is examined as to which point in time an ascending side of a received pulse exceeds a threshold value (S). Detected between a second point in time (t2) and a first point in time (t1), at which the transmission of a pulse of light had begun, a difference (t) corresponds to a running time that depends a distance to be determined.
