Measurement of the local displacement field generated by a microindentation using digital speckle pattern interferometry and its application to investigate coating adhesion
(Elsevier, 2009-05)
This paper presents a technique to investigate the adhesion of thin coatings which combines digital speckle pattern interferometry and an indentation test. The proposed approach is based on the measurement of the local ...
A novel approach for measuring nanometric displacements by correlating speckle interferograms
(Elsevier, 2018-11)
Recently, two phase evaluation methods were proposed to measure nanometric displacements by means of digital speckle pattern interferometry when the phase changes introduced by the deformation are in the range [0, π) rad. ...
Robust phase recovery in temporal speckle pattern interferometry using a 3D directional wavelet transform
(Optical Society of America, 2009-08)
We propose an approach based on a 3D directional wavelet transform to retrieve optical phase distributions in temporal speckle pattern interferometry. We show that this approach can effectively recover phase distributions ...

Probing quantum transport by engineering correlations in a speckle potential
(American Physical Society, 2014-02)
We develop a procedure to modify the correlations of a speckle potential. This procedure, that is suitable for spatial light modulator devices, allows one to increase the localization efficiency of the speckle in a narrow ...
Measurement of shrinkage of composite resin by laser speckle contrast analysis
(Maik Nauka/interperiodica/springer, 2009-12-01)
The aim of this study was to evaluate the shrinkage of a microhybrid dental composite resin photo-activated by one LED with different power densities by means of speckle technique. The dental composite resin Filtek (TM) ...
