A method for optical distance measurement is suggested which comprises executing at least one time-of-flight measurement, wherein a time-of-flight measurement comprises transmitting at least one measuring pulse by means of a transmission unit, reflecting at least one transmitted measuring pulse and receiving at least one reflected measuring pulse by means of a reception unit. The method further comprises generating a backscatter curve based on the time-of-flight measurement and evaluating the backscatter curve for object recognition.

Method and device for optical distance measurement

What is proposed is a method for optically measuring distances, in the case of which a first plurality of measuring pulses is emitted during a first measuring interval by means of a transmitting element of a transmitting unit at first emitting times, and wherein a second plurality of measuring pulses is emitted during a second measuring interval by means of the transmitting element of the transmitting unit at second emitting times. The method comprises the reception of reflected measuring pulses by means of a receiving element of a receiving unit assigned to the transmitting element at receiving times. The method further comprises the determining of a first amount of times-of-flight for each received measuring pulse, wherein the first amount of times-of-flight is determined by using the first emitting times.
