Zusammenfassung:An optoelectronic sensor for measuring a distance using a light time of flight method, comprising a light transmitter for transmitting a light signal, a light receiver having a plurality of light receiving elements for detecting received light, a plurality of light time of flight measuring units for determining respective individual light times of flight, a memory for collecting individual light times of flight, and a control and evaluation unit configured to determine a distance value by evaluating the collected individual light times of flight, wherein a readdressing unit is configured to write individual light times of flight to specific addresses of a same uniform memory depending on the assignment of a light time of flight measuring unit to a group, so that the control and evaluation unit can assign the stored individual light times of flight via the address to a group and thus to a distance value.
