Abstract: Described herein is a detector for determining a position of an object. The detector includes a sensor element having a matrix of optical sensors, wherein the sensor element is configured to determine a reflection image. The detector also includes an evaluation device configured to select a reflection feature of the reflection image at a first image position in the reflection image, determine a longitudinal coordinate z of the selected reflection feature by optimizing a blurring function fa, and determine a reference feature in a reference image at a second image position in the reference image corresponding to the reflection feature. 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 configured to determine the relative spatial constellation from the longitudinal coordinate z and the first and the second image positions.
