Abstract: A detector for optical detection of an object contains a modulation device generating at least one modulated light beam from the object to the detector; a longitudinal optical sensor having at least one sensor region and designed to generate at least one longitudinal sensor signal depending on an illumination of the sensor region by the modulated light beam; and an evaluation device designed to generate at least one item of information on a longitudinal position of the object. The longitudinal sensor signal contains a first component, which depends on a response of the longitudinal optical sensor to a variation of the modulation of the modulated light beam, and a second component, which depends on the total power of the illumination. The item of information is generated by deriving the first component and the second component from the longitudinal sensor signal.
