Abstract

A distance-measuring optoelectronic sensor () for detecting and determining a distance of an object () in a monitoring area (), the sensor () having a light transmitter () for transmitting a transmission signal, a light receiver () for generating a reception signal and a control and evaluation unit () configured to determine a light time of flight from the reception signal and, from that, the distance of the object (), wherein the control and evaluation unit () is further configured to transmit at least one periodically modulated pulse as a transmission signal, to determine a reception time of the pulse in the reception signal and a phase offset of the modulation between transmission signal and reception signal in a neighborhood of the reception time and to determine the distance of the object () from the reception time and the phase offset.
