Holographic Endoscopy

The introduction of holographic metrology into endoscopy is the decisive step towards a metrological basis for a quantitative diagnostic within body cavities, with the advantages of holographic interferometry such as large focal depth imaging, non-destructive, non-contactive, and high-resolving 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 can be used for easy handling and flexibility.
