First, in the oral cavity scanner 100 according to an embodiment of the present invention, the light output unit 221 outputs light (ie, a laser light source) to correspond to an emission angle or an emission position set under the control of the light output controller 222. ) Is output toward the optical system 211. The A-axis coordinate value of the output light projected on the scanning target tooth may be calculated based on the value of the emission angle or the emission position controlled by the light output controller 222.

At this time, the optical system 211 is rotated based on the reflection angle set according to the driving of the optical system driver 212. In detail, the driving controller 213 moves the optical system 211 horizontally back and forth according to the position of the target tooth to be scanned, and drives the optical system driver 212 according to the rotation angle set corresponding to the portion to be scanned to the optical system 211.
