In the course of his research in Interférométrie Speckle — Speckle Interferometry. Cette technique interférométrique permet d'obtenir des champs de déplacements tridimensionnels avec une There has been increasing interest in using laser speckle contrast imaging (LSCI ) as a tool for imaging flow in preclinical research and clinical applications. Laser light reflected by a rough surface produces a curious effect known as speckle, applications of digital speckle pattern interferometry are progressively Feb 8, 2021 Laser Speckle Perfusion Imaging from RWD offers unique non-contact, high time and spatial resolution, rapid imaging for life sciences basic Optical Profiler Characterization of Advanced Materials Using White Light Interferometry.

Laser speckle interferometry

Khetan RP, Chiang FP. A two-dimensional analysis of a double-exposed speckle pattern as created by illuminating a plane surface with a beam of laser light is presented with the role played by the aperture illumination function described in detail. Laser speckle interferometry for plate bending problems. A method is proposed whereby the spatial speckles created in front of a plate with an optically rough surface when illuminated by a coherent laser beam is used to generate slope contour fringes. 2021-01-01 · The electronic speckle pattern interferometry (ESPI) or laser speckle interferometry technique established by Leenderz is a conventional holographic interferometric method that senses in-plane and out-plane displacements of the object by an external force. Speckle interference patterns need in any case a kind of further decoding step in order to become a source of useful information. Thus, while ‘classical interferometry’ (CI) is the unanimously accepted designation for smooth wave interferometry, it could be natural to term ‘SI’ all types of interferences involving speckle waves.
