Characterization of drying paint coatings by dynamic speckle and holographic interferometry measurements

N Budini, C Mulone, N Balducci, FM Vincitorio… - Applied Optics, 2016 - opg.optica.org
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 …

Tuneable algorithms for tracking activity images in dynamic speckle applications

L Buffarini, H Rabal, N Cap, E Grumel, M Trivi… - Optics and Lasers in …, 2020 - Elsevier
Herein we present a generalized algorithm for processing activity images. Existing
algorithms are applicable only to particular cases, and a new, broader approach is therefore …

Activity speckle images obtained from box fractal formalism

NL Cap, H Rabal, E Grumel, L Buffarini, M Trivi… - Optics and Lasers in …, 2019 - Elsevier
We propose a generalized Box Fractal algorithm to segment activity speckle images. The
time history of the intensity value at every pixel of the frames is taken as a time series. The …
