Qualitative characterization of skin tissue with dynamic laser speckle
(Sociedad Argentina de Bioingeniería, 2018-03)
En este trabajo se presenta un estudio preliminar para la caracterización eficaz de la superficie del tejido cutáneo por medio de Speckle Láser Dinámico. Aunque la demoscopia es ampliamente utilizada para realizar este ...
Speckle fields generated with binary diffusers and synthetic pupils implemented on a spatial light modulator
(Optical Society of America, 2015-06)
Digitally controllable Gaussian speckle fields were experimentally generated by implementing binary diffusers and synthetic pupils on a liquid crystal spatial light modulator. The synthetic pupil comprises a Ronchi phase ...

Algorithm For Dynamic Speckle Pattern Processing
(2016)
In this paper we present a new algorithm for determining surface activity by processing speckle pattern images recorded with a CCD camera. Surface activity can be produced by motility or small displacements among other ...
Hydrophilic character study of silica-gel by a laser dynamic speckle method
(Sociedad Cubana de Física, 2008-10)
El trabajo muestra una aplicación de la técnica de speckle dinámico al estudio de hidrofilicidad de sílica gel comercial con diferentes propiedades texturales, tales como tamaño de granos, área superficial y volumen de ...
Assessment of multifractal analysis in dynamic laser speckle signals using a spatial light modulator
(Optical Society of America, 2019-02)
We assess and discuss several technical aspects of the multifractal statistical analysis applied to time series of dynamic speckle intensity signals. Due to the complexity of this goal, we implemented an optical setup that ...
Comparisons between singularities of pseudophase and speckle phase using binary diffusers in optical vortex metrology
(Society of Photo-Optical Instrumentation Engineers, 2016-12)
An analysis based on the comparison between singularities of speckle phase and pseudophase in the practice of optical vortex metrology is carried out by measuring the phase map of the speckle pattern obtained from the ...
Dynamic model for biospeckle
(Optical Soc Amer, 2013-06)
This paper reports the development of a simple dynamic microscopic model to describe the main features of the phenomenon known as dynamic speckle, or biospeckle. Biospeckle is an interference pattern formed when a biological ...
