Claim Text:
1. A dental optical scanning device, comprising: an optical three-dimensional surface scanning system structure including a scan result display section for displaying at least a scan result, a scan control section for controlling a scan, a scanning light emitting section for emitting scanning light, a scanning mirror usable for scanning performed with the scanning light, an exiting opening through which the scanning light is directed toward a scan target, a light transmission path for guiding the scanning light to the exiting opening, an entering opening on which the scanning light directed from the exiting opening is incident after being scattered by the scan target, a light receiving path for guiding the scattered light incident on the entering opening, and a light receiving section for receiving the scattered light guided by the light receiving path; and an optical coherence tomography scanning system structure including a scan result display section for displaying at least a scan result, a scan control section for controlling a scan, a scanning light emitting section for emitting scanning light, a light dividing section for dividing the scanning light into scanning light and reference light, a scanning mirror usable for scanning performed with the scanning light, an exiting opening through which the scanning light is directed toward the scan target, a light transmission path for guiding the scanning light to the exiting opening, an entering opening on which the scanning light directed from the exiting opening is incident after being scattered by the scan target, a light receiving path for guiding the scattered light incident on the entering opening, a reflective mirror for reflecting the reference light obtained as a result of the division performed by the light dividing section, a light interfering section for causing interference of the reflected reference light reflected by the reflective mirror and the scattered light, and a coherent light receiving section for receiving coherent light generated by the interference performed by the light interfering section; wherein:
