Abstract

We present a fringe projection system embedded into an endoscope to describe the absolute shape of an inspected object. A fringe pattern generated by launching incoherent light waves into a volume hologram is projected on the inspected surface. The endoscope observes the projected fringes at another point of view. Fringes on the obtained image are deformed both by the topography of the object, and are analyzable to retrieve the 3D shape.
