Intraoral scanner

Abstract

This intraoral scanner comprises: a light source unit configured to emit light along an axis of emission; a first optical system which reflects, along a first optical path, light emitted from the light source unit; a second optical system which reflects, toward a subject, light reflected from the first optical system; and a third optical system which forms, together with the second optical system, a pair of second optical paths spaced apart from each other in the widthwise direction, the third optical system reflecting, to an image sensor unit, light reflected from the subject to the second optical system and reflected along the pair of second optical paths. The first optical system is configured to reflect light emitted along the axis of emission such that the reflected light travels along the first optical path spaced apart therefrom in the widthwise direction.
