Abstract
An optoelectronic sensor for measuring a distance comprises a light transmitter () for transmitting a sequence of individual light pulses () and a light receiver () for receiving the individual light pulses (). An individual time of flight measuring unit () determines a sequence of individual times of flight of the individual light pulses () as the duration between a transmission point in time and its reception point in time. An evaluation unit () accumulates individual times of flight and determines a common measurement value for the distance from the accumulated individual times of flight. The evaluation unit () comprises a filter () for accumulating an individual time of flight only if it coincides, within a time window, with a preceding individual time of flight.
