Intraoral scanner

An intraoral scanner comprising:

• a case having an opening part formed at a front portion of the intraoral scanner;
• a light source part disposed apart from a front portion of the intraoral scanner and configured to emit light;
• a first optical system including a first reflector configured to reflect the light emitted from the light source part and a second reflector configured to reflect the light reflected by the first reflector toward the opening part;
• a second optical system including one reflector that forms a first optical path with the second reflector, the second optical system being configured to reflect the light reflected from the first optical system toward a subject through the opening part and to reflect the light reflected from the subject toward the inside of the case;
• a third optical system configured to reflect the light reflected from the one reflector of the second optical system, the third optical system being disposed such that it forms a pair of second optical paths with the one reflector of the second optical system without interfering with the second reflector forming the first optical path;
• and
• an image sensor part configured to detect the light refracted by the third optical system.
