Abstract: An intraoral scanner includes a light source to generate light that is to be output onto an object external to the intraoral scanner. The intraoral scanner further includes an optical system comprising a projection subsystem and an imaging subsystem that are combined such that projection optics of the projection subsystem and imaging optics of the imaging subsystem share one or more lenses and an optical path, wherein the light is to travel the optical path in a first direction to illuminate the object external to the intraoral scanner, and wherein reflected light that has been reflected off of the object external to the intraoral scanner is to travel the optical path in a second direction that is opposite the first direction. The intraoral scanner further includes an image sensor configured to receive the reflected light that has been reflected off of the object external to the intraoral scanner.
