Paper Abstract

The combination of holographic metrology with endoscopic imaging allows the development of a new class of minute instruments for high-resolving, non-contactive, non-destructive intra-cavity measurements. New developments in micro-optics give main impulses to actual progress in holographic endoscopy: - Assembled gradient-index rod lenses are used for small submillimeter needle diameter rigid endoscopic instruments. - The use of (single-mode) optical fibers offers easy handling and flexibility. Especially, new single-mode imaging fiber bundles show improved performance data (high lateral resolution) at very small diameters. - The use of electro-optical crystals opens the possibility of developing a minute holographic storage device for an easy-to-handle, small holographic endoscopic camera system for in-situ recording, reconstruction and erasure with fast repetition rate.
