Abstract: An intraoral scanner according to an embodiment includes a case having an opening part formed at one end thereof, a light source part disposed inside the case and configured to emit light, a first optical system disposed at the opening part and configured to reflect the light emitted from the light source part toward a subject located outside the case, a second optical system disposed adjacent to the first optical system and configured to reflect light reflected from the subject toward the inside of the case, and an image sensor part configured to detect the light reflected by the second optical system.

Abstract: An intraoral scanner includes a case having an opening part at one end thereof, a light source part at the other end of the case and configured to emit light, a first optical system including a first reflector to reflect the light emitted from the light source part and a second reflector disposed apart from the first reflector to reflect the light reflected by the first reflector toward the opening part, a second optical system in the opening part to reflect the light reflected from the first optical system toward a subject and reflect light reflected from the subject toward the second reflector, a third optical system adjacent to a back surface in the opposite direction of a reflective surface of the second reflector to reflect the light reflected from the second optical system, and an image sensor part to detect the light reflected from the third optical system.
