Abstract

The present inventive concept relates to an optical coherence tomography (OCT)-based intraoral scanner calibration device including: a light source; an optical coupler for splitting the path of light irradiated from the light source in first light and second light; a reference part for generating reference light from the first light split by the optical coupler; a sample part for generating measurement light from the second light split by the optical coupler; and a signal generator for generating an OCT image from the reference light and the measurement light.
