Abstract
A detector having a transversal optical sensor adapted to determine a transversal position of at least one light beam traveling from an object to the detector and a longitudinal optical sensor having at least one sensor region. The longitudinal optical sensor is designed to affect at least one longitudinal sensor signal in a manner dependent on an illumination of the sensor region by the light beam. 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.

A detector, comprising:
- a transversal optical sensor, the transversal optical sensor being adapted to determine a transversal position of at least one light beam traveling from an object to the detector, the transversal position being a position in at least one dimension perpendicular to an optical axis of the detector, the transversal optical sensor being adapted to affect at least one transversal sensor signal;
- and
- a longitudinal optical sensor, wherein the longitudinal optical sensor has at least one sensor region, wherein the longitudinal optical sensor is designed to affect at least one longitudinal sensor signal in a manner dependent on an illumination of the sensor region by the light beam, 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.
A method for scanning an environment,
- wherein at least one transversal optical sensor of a detector is used, wherein the transversal optical sensor determines a transversal position of at least one light beam traveling from the environment to the detector, the transversal position being a position in at least one dimension perpendicular to an optical axis of the detector, wherein the transversal optical sensor affects at least one transversal sensor signal;
- and
- wherein at least one longitudinal optical sensor of the detector is used, wherein the longitudinal optical sensor has at least one sensor region, wherein the longitudinal optical sensor generates at least one longitudinal sensor signal in a manner dependent on an illumination of the sensor region by the light beam, 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.
