1. An optoelectronic sensor for the measurement of distances in accordance with the light transit time principle, comprising:

  • a light transmitter configured to transmit a light signal;

    a light receiver configured to receive at least one of a remitted and a reflected received signal;

    an evaluation unit configured to satisfy a transition condition for the received signal by systematic selection of a transmission delay time for transmission of the light signal at an observation time and configured to calculate the light transit time from the transmission delay time; and

    a regulator configured to adjust the transmission delay time such that the transition condition is satisfied at the observation time.
