In this paper, we present a 3D surface imaging technique to re-engineer traditional endoscopy into a quantitatively capable instrument. In our design concept, we demonstrate that, by utilizing two fiber bundle channels and structured light based 3D reconstruction principle, we can obtain the 3D information on a GI tract surface in all most real time fashion. The two fiber bundles are used for pattern light projection and image capture. The implied significance of our design and experiment includes: (a) It is possible to convert the traditional 2D video based endoscope into a 3D endoscope through minimum modifications; and (b) The proposed 3D endoscope allows clinicians to obtain the actual size information on any target of interest during the procedures.
