Digital holographic interferometry is a coherent-optical method for noncontacting measurement of full field deformations in the micrometer-range. While deformations in the range of the wavelength of the used laser-light are determined by comparison of the phases of the wave fields reconstructed from
Simple optical glass is used in digital holographic set up to scan and record holograms of a large object. Dimension of the object is such that it does not satisfy sampling theorem. Experimental results and calculations illustrate that an optical slab can be used to scan the surface of the large obj
The paper presents the use of Holographic Interferometry and Electronic Speckle Pattern Interferometry for the measurement of dynamic surface displacements. A concise theoretical background of the optical phenomena on which the two techniques are based is given. Analysis of holographic and speckle f
