Tomography fusion type oral cavity scanner

The present invention discloses a tomographic fusion type oral cavity scanner, comprising: an oral cavity scanning unit including a projector including a first light source generating visible light and a camera receiving the visible light incident to teeth and reflecting the visible light to generate image data; the optical tomography scanning part comprises an OCT (Optical Coherence Tomography) body and an OCT scanning probe; the OCT body includes a second light source that generates measurement light incident on teeth, a beam splitter that splits the measurement light into reference light and the measurement light, a reference mirror that reflects the reference light, and a light detector that detects interference light generated by overlapping of signal light generated by reflection of the measurement light by the teeth and the reference light reflected by the reference mirror. The OCT scanning probe comprises a collimator for converting measuring light into parallel light and an MEMS (Micro Electro Mechan
