1. An intra-oral scanner, comprising:
a first scanner configured to operate in a first wavelength range to obtain first scan data from a surface of a target using a first optical path, the first scan data comprising a first three-dimensional image of the surface of the target, and the first scanner comprising a TIR prism comprising a first right triangle prism and a second triangle prism shaped like a wedge having angles of 90°, approximately 21°, and approximately 69°;
a second scanner configured to operate in a second wavelength range to obtain second scan data at video speed from a volume underlying the surface of the target using a second optical path, the second scan data comprising a second three-dimensional image of the volume underlying the surface of the target; and
a housing configured to support the first scanner and the second scanner;
wherein a first portion of the first optical path is common with a first portion of the second optical path; and
wherein a second portion of the first optical path is parallel to a second portion of the second optical path.
