Abstract: A method for detecting an edge of an object is carried out by means of a detection device (10), which has an emission region running along a first straight line and has a receiving region which runs along a second straight line, which is arranged in parallel to the first straight line. An emission subregion (11a-p) of the emission region is selected, which extends up to a first end of the emission region. Light is emitted from the emission subregion (11a-p) and a light signal of light reflected on the object is received in the receiving region. The emission subregion (11a-p) is then shifted along the first straight line in the direction of a second end of the emission region. Emitting, receiving and shifting are repeated until the emission subregion (11a-p) extends up to the second end at the start of the shifting step. A signal course is compiled from the received light signals, and the detection of the edge from the signal course is carried out.
