The combination of holographic metrology with endoscopic imaging allows the development of a new class of minute instruments for high-resolving, noncontactive, non-destructive quantitative diagnostics within body cavities. This includes the analysis of structure, form, deformation and vibration of the object under study. There are two possibilities of holographic endoscopic recording: at the distal end within the instrument or with an external holographic camera. In both cases optical fibers are essential for easy handling and flexibility of the holographic endoscopic system. Avantages and drawbacks of optical fiber use are discussed and examples of medical applications are presented.
