ABSTRACT:
A device for use in a dental or medical application to obtain three-dimensional contour information comprises a multiplicity of arm segments, first mounting elements for connecting the arm segments to one another to form an articulated assembly of the arm segments. A second mounting element serves to fix the articulated assembly relative to a person's head, while a third mounting element is provided for attaching a diagnostic or medical treatment instrument to the articulated assembly at a point spaced from the second mounting element. A feedback component or components are operatively coupled with at least some of the arm segments for providing electrical signal feedback data as to positions of the arm segments relative to one another, thereby providing information as to the position of the instrument relative to the person's head.
