Paper Abstract

Endoscopy has become established as a technique for visual inspection in difficult to access environments. So far it has not exceeded beyond the observation purpose. When a three- dimensional object is imaged by means of an endoscope, only a two-dimensional display is possible. In modern diagnostics, however, it can be necessary to know the size and shape of the object under study or to perform some deformation analysis. The methods for reconstructing the 3-D object shape from a 2-D endoscopic image are described and illustrated with some examples. They exploit holographic and non-holographic techniques for contour generation. Endoscopic deformation analyses with internal and external holographic recording are demonstrated as well.
