Abstract: 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.

Abstract: An optoelectronic sensor for determining the distance of an object having a light transmitter for transmitting a light pulse; having a SPAD light receiver with a measurement reception element and a reference reception element; and having an evaluation unit that is configured to determine a time of flight between the transmission of the light pulse and the reception of the remitted light pulse and from this the distance of the object from the received signals of the measurement reception element and of the reference reception element. The invention further relates to a method of determining an object in a monitored zone.
