“…Yet, suppression of such reflections can be provided by appropriate positioning or shaping of the glass rod in combination with holographic subtraction [7,8,9]. Holographic subtraction is realized by an 180° optical phase shift of the laser light between the two exposures of a double-exposure holographic record in either the object beam or reference beam.…”

Increasing miniaturization is required in many domains of optical instrumentation, such as in the development of endoscopic devices.In combination with coherent metrology, especially holographic interferometry, a new class of minute instruments can be developed for high -resolving, non -contactive, non -destructive intra-cavity measurements. Three developments in micro -optics give main impulses to actual progress in holographic endoscopy: -micro -optical gradient -index imaging systems, -micro -optical (single -mode) imaging fiber bundles, and -electro-optical crystals as (micro -optical) holographic storage devices.three -dimensionality of the reconstructed image with a large focal depth as well as 50 ABSTRACTIncreasing miniaturization is required in many domains of optical instrumentation , such as in the development of endoscopic devices.In combination with coherent metrology, especially holographic interferometry, a new class of minute instruments can be developed for high-resolving, non-contactive f non-destructive intra-cavity measurements.
