    Abstract: A non-transitory medium includes instructions for generating a three-dimensional virtual model of an intraoral object by receiving surface scan data of the intraoral object while changing a position of at least one lens of focusing optics of an intraoral scanner, wherein the surface scan data comprises data for a plurality of points of the intraoral object, and adjusting the data for one or more of the plurality of points to compensate for one or more inaccuracies associated with changes of a shape of a focusing surface. A three-dimensional virtual model of the intraoral object is generated using the adjusted data.

    Abstract: Embodiments are directed to an imaging apparatus, which in an embodiment includes a light source to provide light, optics, a translation mechanism and a detector. The optics include focusing optics to perform focusing of the light onto a non-flat focal surface and to direct the light toward a three dimensional object. The translation mechanism adjusts a location of at least one lens of the focusing optics to displace the non-flat focal surface. The detector measures intensities of returning light that is reflected off of the three dimensional object, wherein the intensities of the returning light are measured for a plurality of locations of the at least one lens for determination of positions of a plurality of points of the three dimensional object. Detected positions of one or more of the plurality of points are adjusted to compensate for the non-flat focal surface.

    Abstract: A confocal imaging apparatus includes an illumination module to generate an array of light beams. Focusing optics perform confocal focusing of an array of light beams onto a non-flat focal surface and direct the array of light beams toward a three dimensional object to be imaged. A translation mechanism adjusts a location of at least one lens to displace the non-flat focal surface along an imaging axis. A detector measures intensities of an array of returning light beams that are reflected off of the three dimensional object and directed back through the focusing optics. Intensities of the array of returning light beams are measured for locations of the at least one lens for determination of positions on the imaging axis of points of the three dimensional object. Detected positions of one or more points are adjusted to compensate for the non-flat focal surface.

    Abstract translation: 共焦成像装置包括用于产生光束阵列的照明模块。 聚焦光学器件将光束阵列的共聚焦聚焦执行到非平坦焦点表面上，并将光束阵列引向待成像的三维物体。 平移机构调节至少一个透镜的位置以沿成像轴移动非平坦焦点表面。 检测器测量从三维物体反射并返回通过聚焦光学器件的返回光束阵列的强度。 测量返回光束阵列的强度用于确定三维物体的点的成像轴上的位置的至少一个透镜的位置。 调整一个或多个点的检测位置以补偿非平坦焦点表面。
