A method for detecting an edge of an object is carried out by means of a detection device (10), which has a transmission 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. A transmission subregion (11a-p) of the transmission region is selected, which extends up to a first end of the transmission region. Light is transmitted from the transmission subregion (11a-p) and a light signal of light reflected on the object is received in the receiving region. The transmission subregion (11a-p) is then shifted along the first straight line in the direction of a second end of the transmission region. Transmitting, receiving and shifting are repeated until the transmission 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.
