Abstract

An optoelectronic sensor is provided for measuring the distance from an object in a monitored zone that has a light transmitter for transmitting light signals into the monitored zone; a light receiver having at least one avalanche photodiode operated in Geiger mode for receiving the light signals reflected or remitted by the object; an individual time of flight measurement unit for determining an individual time of flight of a light signal from the sensor to the object; and an evaluation unit that is configured to generate a common measured value for the distance from a plurality of individual times of flight.
