1. A scanning system for determining a position of at least one object, said scanning system comprising at least one detector comprising:

  • at least one longitudinal optical sensor, wherein the longitudinal optical sensor has at least one sensor region, wherein the longitudinal optical sensor is at least partially transparent, wherein the longitudinal optical sensor is designed to generate at least one longitudinal sensor signal in a manner dependent on an illumination of the sensor region by at least one light beam traveling from the object to the detector, wherein the longitudinal sensor signal, given the same total power of the illumination, is dependent on a beam cross-section of the light beam in the sensor region;

    at least one illumination source adapted to scan illumination light through at least one scan region in space and illuminate the at least one object with the illumination light through the longitudinal optical sensor; and

    at least one evaluation device, wherein the at least one evaluation device is designed to generate at least one item of information on a longitudinal position of at least one point of the at least one object in said scan region relative to the at least one detector by evaluating the longitudinal sensor signal.
