OG exemplary drawing
 
1. A handheld intraoral scanner for determining a 3D geometry of an object in an oral cavity, the intraoral scanner comprising:
a tip configured to be inserted into the oral cavity;
at least one camera accommodating an array of sensor elements;
a pattern generator configured to generate, using a light source, a static pattern or a time-varying illumination pattern; and
an optical system configured to transmit the static pattern or the time-varying illumination pattern, via the tip, towards the object along an optical path thereby illuminating at least a part of the object with the static pattern or the time-varying illumination pattern, and to transmit at least a part of the light returned from the object to the at least one camera to form a plurality of 2D images, wherein the plurality of 2D images is configured to determine a 3D geometry; and
wherein the handheld intraoral scanner is wireless.
