Abstract

A detector for determining a position of at least one object is disclosed and includes at least one sensor element having a matrix of optical sensors, the optical sensors each having a light-sensitive area. 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. The sensor element is adapted to determine at least one reflection image. The detector also includes at least one evaluation device adapted to select at least one reflection feature of the reflection image at least one first image position in the reflection image. The evaluation device is adapted to determine at least one reference feature in at least one reference image and at least one second image position in the reference image corresponding to the at least one reflection feature.
