Revealing RCOR2 as a regulatory component of nuclear speckles
(2021)
Background: Nuclear processes such as transcription and RNA maturation can be impacted by subnuclear compartmentalization in condensates and nuclear bodies. Here, we characterize the nature of nuclear granules formed by ...
Comparison of phase recovery methods in spiral speckle pattern interferometry correlation fringes
(Elsevier, 2016-05)
Spiral interferometry can be used as a solution to the problem of sign ambiguity presented in the conventional speckle pattern interferometric technique when the optical phase needs to be reconstructed from a single closed ...
A new wavelet family for speckle noise reduction in medical ultrasound images
(Universidade Federal de São Paulo (UNIFESP), 2019-08-29)
Ultrasonography is highly used as an image tool for medical diagnosis due to its noninvasive nature, low cost, adaptability, and the possibility of real-time visualization. However, the noise present in these images makes ...

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 ...
Characterization of drying paint coatings by dynamic speckle and holographic interferometry measurements
(Optical Society of America, 2016-05)
In this work we implemented dynamic speckle and holographic interferometry techniques to characterize the drying process of solvent-based paint coatings. We propose a simple way to estimate drying time by measuring speckle ...
Measurement of in-plane displacements using the phase singularities generated by directional wavelet transforms of speckle pattern images
(Optical Society of America, 2013-03)
We present a method to determine micro and nano in-plane displacements based on the phase singularities generated by application of directional wavelet transforms to speckle pattern images. The spatial distribution of the ...
