Abstract: A method for determining a distance of an object with the aid of an optical detection apparatus and such an apparatus are described. A light signal pulse is emitted and reflected at the object, and is received as an echo light signal pulse. The echo light signal pulse is divided upon reception into temporally successive discrete reception time windows and converted into corresponding electrical energy. The end of the respective conversion is in each case assigned as the sampling time to the corresponding time window. The electrical energies of the time windows are compared in each case with a threshold value. As soon as the electrical energy of a first reference reception time window is greater than the threshold value, a linear interpolation of the temporal profile of the discrete electrical reception signal is carried out temporally before the sampling time of the first reference time window.
