Abstract
A 3D dental camera for recording surface structures of an object by means of triangulation. The camera includes a light source for producing an illumination beam, means for focusing the illumination beam onto the surface of the object, an image sensor for recording a monitoring beam that is the illumination beam reflected by the surface of the object, and means for focusing the monitoring beam onto the image sensor. The light source is subdivided into a plurality of regions that can be independently regulated in terms of light intensity, such that a light center of the illumination beam changes in at least two switching modes of the light source.
