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; andat 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. 2. The scanning system according to claim 1, wherein the evaluation device is designed to generate the at least one item of information on the longitudinal position of the at least one object from at least one predefined relationship between a geometry of the illumination of the sensor region by the light beam and a relative positioning of the at least one object with respect to the at least one detector. 3. The scanning system according to claim 2, wherein the predefined relationship between the geometry of the illumination of the sensor region by the light beam and the relative positioning of the at least one object with respect to the at least one detector is taking account of a known power of the illumination. 4. The scanning system according to claim 2, wherein the predefined relationship between the geometry of the illumination of the sensor region by the light beam and the relative positioning of the at least one object with respect to the at least one detector is taking account of a modulation frequency with which the illumination light is modulated. 5.

The scanning system according to claim 1, wherein the at least one illumination source adapted to scan illumination light through at least one scan region in space scans the illumination light through the at least one scan region in a stepwise fashion. 10. The scanning system according to claim 1, wherein the at least one detector further comprises at least one reflective element, wherein the at least one reflective element is adapted to reflect the illumination light before illuminating the at least one object. 11. The scanning system according to claim 10, wherein the at least one reflective element is a movable reflective element adapted to be adjusted to at least two different positions, wherein, in the at least two different positions, the illumination light is reflected into different directions. 12.
