1. 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 reflection 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, wherein the evaluation device is configured for determining at least one longitudinal region of the selected reflection feature of the reflection image by evaluating a combined signal Q from the sensor signals, wherein the evaluation device is adapted to determine at least one displacement region in at least one reference image corresponding to the longitudinal region, wherein the evaluation device is adapted to match the selected reflection feature with at least one reference feature within the displacement region.
