An apparatus for acquiring intraoral images of a subject has an OCT imaging apparatus having an OCT light source, a scanner that conveys OCT light toward the subject and returned from the subject, and an interferometer having a reference arm and a sample arm. A reflectance imaging apparatus has a visible light source directed toward the subject and an image sensor that forms a reflectance image from returned light. Processing and control logic are configured to process and combine the returned reflectance image to the OCT measured data. A display shows the combined reflectance image and OCT measured data.
