摘要： A chromatic confocal technique and apparatus for the rapid three-dimensional measurement of an object shape, particularly of a tooth in a patient's jaw, using an array of polychromatic point light sources, a planar detector matrix, a beam splitter for lateral spectral separation, and an objective for illuminating and recording the object. Spectral defined reference light bundles are generated, injected into the detection beam path via a reference beam path and, following spectral splitting, are focused on the detector matrix as reference image points, wherein laterally shifted sub-matrices are numerically defined on the detector matrix for spectral analysis of the object light, which sub-matrices are implemented as spectral cells for three-dimensional measurement of the shape of the object.

摘要： The invention relates to a chromatic confocal technique method and arrangement for the rapid three-dimensional measurement, in particular, of object shape, more particularly of a tooth in the jaw of a human being with an array of polychromatic point light sources, a planar detector matrix, arranged before means for lateral spectral separation and an objective for object illuminating and recording. According to the invention, spectral defined reference light bundles are generated also using components of the arrays of point light sources for chromatic calibration, wherein said reference light bundles are injected into the detection beam path via a reference bean path for chromatic lateral separation and then focused on the detector matrix as reference image points. Spectral reference points are calculated at the detector matrix positions and sub-matrices for spectral analysis of object light are digitally stored with pixel accuracy by means of the above positions which then serve for obtaining measurement points such that the detector matrix may be completely filled out with oblong sub-matrices, the planar array is arranged on the planar detector matrix rotated about an acute angle to the spectral axis, wherein the rotation is carried out about the optical axis (OA) of the arrangement, such that a connecting line of point light sources on projection thereof in the plane of the detector matrix includes an acute angle there with the spectral axis, the λ-axis.
