Abstract: An apparatus for dental imaging comprises a light source for generating light, an optics system for focusing the light, and a probe head. The light source, the optics system and the probe head are arranged such that the light passes through the optics system, passes through the probe head, and exits the probe head. The optics system is configured such that chief rays of the light before entering the probe head are divergent to each other, wherein an angle defined by a marginal ray of an outermost beam of the light is complementary to an angle defined by an extreme off-axis chief ray of the light with respect to the optical axis.

Abstract: An apparatus is described for measuring surface topography of a patient's teeth. The apparatus may include an optical probe, a light source configured to generate incident light, and focusing optics configured to focus the incident light to a focal plane external to the optical probe, wherein the focal plane is a diagonal focal plane that is non-orthogonal to a direction of propagation of the incident light. The apparatus may further include a light sensor configured to measure a characteristic of returned light generated by illuminating the patient's teeth with the incident light, and a processing unit operable to determine the surface topography of the patient's teeth based on the measured characteristic of the returned light.

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: A system for intraoral scanning includes a display, a processing unit, and a scanner to generate scan data and viewfinder images of an intraoral cavity. The processing unit is to: receive the scan data and the viewfinder images; generate a 3D model of the intraoral cavity using the intraoral scan data; output the 3D model to the display; output the viewfinder images to the display; determine which portions of the intraoral cavity have been scanned; determine a current field of view of the scanner; determine, based on the current field of view and the determined portions of the intraoral cavity that have been scanned, a visual indicator that provides guidance for positioning and orienting the field of view of the scanner; and output the visual indicator to the display.

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: An imaging apparatus includes a first and second light source, focusing optics, a probe, a detector, an optical transmission medium and a color sensor. The first light source is to generate light beams that travel through the focusing optics along an optical path to the probe. The probe directs the light beams toward a three dimensional object to be imaged. The detector detects returning light beams that are reflected off of the three dimensional object and directed back through the probe and the focusing optics. The second light source is to generate multi-chromatic light. The optical transmission medium is outside of the optical path and is to receive a ray of the multi-chromatic light reflected off of a spot on the three dimensional object and through the probe. The color sensor is to receive the ray from the optical transmission medium and determine a color of the spot on the three dimensional object.

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: 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.
