The invention relates to a 3D dental camera for recording surface structures of a measuring object (2) by means of triangulation, said camera comprising a light source (3) for producing an illumination beam (7.1, 7.2, 7.3), means for focusing the illumination beam (7.1, 7.2, 7.3) onto the surface of the measuring object, an image sensor (6) for receiving an illumination beam (7.1, 7.2, 7.3) reflected by the surface of the measuring object (2) in the form of an observation beam (9.1, 9.2, 9.3), and means (5) for focusing the observation beam (9.1, 9.2, 9.3) onto the image sensor (6). The light source (3) is split into a plurality of regions (3.1, 3.2, 3.3) that can be independently regulated in terms of the light intensity thereof, in such a way that a light centre position (10.1, 10.2, 10.3) of the illumination beam (7.1, 7.2, 7.3) changes in at least two switching modes. |
