Zusammenfassung:The application relates to an optoelectronic sensor and method of measuring the distance from an object. An optoelectronic sensor for measuring the distance from an object in a monitored zone is provided that has a light transmitter for transmitting individual light signals into the monitored zone; a light receiver having at least one avalanche photodiode operated in Geiger mode for receiving theindividual light pulses reflected or remitted by the object; an individual time of flight measurement unit for determining an individual time of flight of an individual light pulse as a duration between a transmitted point in time of the respective individual light pulse and its received point in time at the avalanche photodiode; and an evaluation unit that is configured to determine a common measured value for the distance from a plurality of individual times of flight and to estimate how many individual times of flight are to be expected in a time interval on the basis of background events. 本申请涉及用于测量到对象的距离的光电传感器和方法。
