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
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
