Abstract: An exemplary optical apparatus has an OCT imaging apparatus with a first light source for low coherence light of wavelengths above a threshold wavelength and a signal detector that obtains an interference signal between low coherence light from the sample and low coherence light reflected from a reference. A surface contour imaging apparatus has a second light source that emits one or more wavelengths of surface illumination below the threshold wavelength, a camera to acquire images from illumination reflected from the sample. The exemplary optical apparatus and/or exemplary methods for using the same can provide reduced errors in generating a dental 3D surface mesh.

Abstract: Exemplary method and/or apparatus embodiments for intraoral imaging modify the gums of a patient with indicia, spaced apart over a region of interest. Optical images for surface contour, spanning the region of interest, are acquired, with reflectance images of the region of interest that include the indicia. Exemplary method and/or apparatus embodiments form patch mesh images from the surface contour images, wherein each patch mesh image characterizes the surface contour of a partial portion of the region of interest. The patch mesh images are combined to form a mesh representative of the region of interest according to the plurality of reflectance images of the indicia. The mesh representative of the region of interest can be displayed, stored, or transmitted.
