<p>The camera has an objective (11) and a deflecting mirror (14) arranged inside a housing (2.1) comprising a fastening bolt. The objective is arranged such that light radiation (6.1), originating from a light source (6) are focused on an object (13) e.g. rear molar teeth, to be measured. Position measuring units detect two position markings of a scanning unit (21), where the measuring units are provided as a part of the bolt. A control unit controls a predetermined target velocity of the scanning unit as function of a position and time of the scanning unit.</p> |
