Abstract: A system includes an intraoral scanner and a computing device operatively connected to the intraoral scanner. The intraoral scanner generates three-dimensional scan data of a tooth and further performs color measurements of the tooth. The computing device receives the three-dimensional scan data of the tooth during a first mode of operation. The computing device invokes a second mode of operation, and presents, in a graphical user interface (GUI), an image of the tooth. The computing device further presents, in the GUI, data indicating a plurality of color zones of the tooth and further indicating, for at least one color zone of the plurality of color zones, that insufficient color information has been received, wherein each color zone indicates a separate region of the tooth that is expected to have approximately uniform color.

Abstract: An apparatus for dental confocal imaging comprises an illumination module for generating an array of light beams, an optics system for confocal focusing of the array of light beams and a probe head with a light-guiding part having an entrance face and an exit face. The illumination module, the optics system and the probe head are arranged such that the array of light beams from the illumination module passes through the optics system, enters the light-guiding part via the entrance face and exits the light-guiding part via the exit face. The optics system is configured such that, after having passed through the optics system, the outermost marginal rays of the outermost light beams with respect to the optical axis of the optics system are parallel or divergent to the optical axis.

Abstract: An apparatus is described for measuring surface topography of a three-dimensional structure. In many embodiments, the apparatus is configured to focus each of a plurality of light beams to a respective fixed focal position relative to the apparatus. The apparatus measures a characteristic of each of a plurality of returned light beams that are generated by illuminating the three-dimensional structure with the light beams. The characteristic is measured for a plurality of different positions and/or orientations between the apparatus and the three-dimensional structure. Surface topography of the three-dimensional structure is determined based at least in part on the measured characteristic of the returned light beams for the plurality of different positions and/or orientations between the apparatus and the three-dimensional structure.

Abstract: A probe head for dental confocal imaging, comprises a light-guiding part for guiding a light beam towards a teeth portion, the light-guiding part having an entrance face through which the light beam enters the light-guiding part and an exit face through which the light beam exits the light-guiding part, wherein the light-guiding part is configured, in case of a linearly polarized light beam having two polarization components being perpendicular to each other, to change polarization of the linearly polarized light beam on its path through the light-guiding part in such a way that one of the two polarization components, compared to the other of the two polarization components, is retarded by an odd multiple of a quarter of a wavelength of the light beam along the path from the entrance face to the exit face.

Abstract: An intraoral scanner comprises one or more structured light projectors and two or more cameras, where each structured light projector projects a pattern of light onto an intraoral three-dimensional (3D) surface and the two or more cameras capture one or more sets of images, wherein each image includes at least a portion of the projected pattern of light. A processor solves a correspondence problem within a set of images of the one or more sets of images such that points in 3D space are determined based on correspondence of captured features in the set of images to projected features of at least the portion of the projected pattern, wherein said points in 3D space form a solution to the correspondence problem. The processor calibrates the intraoral scanner by performing an adjustment to stored calibration data associated with the intraoral scanner based on the solution to the correspondence problem.
