Abstract
An apparatus for intraoral three-dimensional (3D) scanning comprises a light source, a spatial pattern, a beam splitter, an optical system comprising fewer than 10 lenses, a mirror, an image sensor, and a depth scanning module. The depth scanning module is configured to axially translate one or more lenses of the optical system in the optical axis to change a focus setting of the optical system, wherein the depth scanning module is configured to axially translate the one or more lenses by 0.1-5 mm to achieve a depth scanning range of 5-40 mm at a scan speed of about 5-50 scans per second.
