Abstract

A detector having a transversal optical sensor adapted to determine a transversal position of at least one light beam traveling from an object to the detector and a longitudinal optical sensor having at least one sensor region. The longitudinal optical sensor is designed to affect at least one longitudinal sensor signal in a manner dependent on an illumination of the sensor region by the light beam. The longitudinal sensor signal, given the same total power of the illumination, is dependent on a beam cross-section of the light beam in the sensor region.
