Detector for determining a position of at least one object comprising at least one device to determine relative spatial constellation from a longitudinal coordinate of the object and the positions of reflection image and reference image

A detector for determining a position of at least one object, the detector comprising:

• at least one sensor element having a matrix of optical sensors, the optical sensors each having a light-sensitive area, wherein each optical sensor is designed to generate at least one sensor signal in response to an illumination of its respective light-sensitive area by a light beam propagating from the object to the detector, wherein the sensor element is adapted to determine at least one reflection image;
• and
• at least one evaluation device, wherein the evaluation device is adapted to select at least one reflection feature of the reflection image at at least one first image position in the reflection image, wherein the evaluation device is configured for determining at least one longitudinal coordinate z of the object by evaluating a combined signal Q from the sensor signals, wherein the evaluation device is adapted to determine at least one reference feature in at least one reference image at at least one second image position in the reference image corresponding to the at least one reflection feature, wherein the reference image and the reflection image are determined at two different spatial configurations, wherein the spatial configurations differ by a relative spatial constellation, wherein the evaluation device is adapted to determine the relative spatial constellation from the longitudinal coordinate z and the first and second image positions.
