An optical 3D measurement probe (1) for measuring the three-dimensional geometry of teeth in the buccal cavity is to be configured such that it is possible to conduct on the same object a plurality of known measurement procedures such as triangulation, light section, phase shifting, stereo photogrammetry and a series of further optical 3D measurement variants, known from industrial metrology, such as, e.g., Graycode-coded optical grating. This is achieved when the probe (1) contains a high-resolution two-dimensional point-wise programmable matrix light source (7, 8), when a digitised projection pattern is stored in an image store (5) and modulates the matrix light source (7, 8) via a video interface (9), and when this image is projected via a projecting optical system (6) onto the tooth surface to be measured. <IMAGE> |
