Abstract
A tomography convergence-type oral scanner includes an oral scanning unit comprising a projector including a first light source for generating visible light, and a camera for generating image data by receiving the visible light reflected from a tooth; an optical tomography scanning unit comprising an OCT body including a second light source that has a different wavelength from the first light source and generates a measurement light incident on the tooth, a beam splitter for splitting the measurement light into a reference light and a measurement light, a reference mirror that reflects the reference light, and a photodetector for detecting an interference light, and an OCT scan probe including a collimator for converting the measurement light into a parallel light and a MEMS mirror for reflecting the converted parallel light; and a dichroic mirror for transmitting the visible light and reflecting the parallel light, thereby irradiating a tooth to be measured.
