Abstract: An optical detection apparatus is configured to transmit pulses into a detection zone after one another in different directions which follow one another in a scanning direction over a scanning angle, to receive the radiation of the transmitted pulses returning from the detection zone, to generate a received signal with respect to each transmitted pulse, said received signal depending on the variation with time of the returning radiation of the transmitted pulse, and to average the received signals of a group of transmitted pulses to generate an averaged received signal. The angular extent relating to the scanning angle of at least one transmitted pulse of the group at a spacing from the detection apparatus disposed within the detection zone is at most 25 times the size of the angular spacing relating to the scanning angle between two transmitted pulses of the group directly adjacent one another in the scanning direction.
