Multiscale permutation entropy analysis of laser beam wandering in isotropic turbulence
Felipe Olivares, Luciano Zunino, Damián Gulich +2
We have experimentally quantified the temporal structural diversity from the coordinate fluctuations of a laser beam propagating through isotropic optical turbulence. The main focu…
Turbulence-induced persistence in laser beam wandering
Luciano Zunino, Damián Gulich, Gustavo Funes +1
We have experimentally confirmed the presence of long-memory correlations in the wandering of a thin Gaussian laser beam over a screen after propagating through a turbulent medium.…
Multifractal characteristics of optical turbulence measured through a single beam holographic process
Dario G. Perez, Regis Barille, Yohann Morille +2
We have previously shown that azopolymer thin films exposed to coherent light that has travelled through a turbulent medium produces a surface relief grating containing information…
Wavelet entropy of stochastic processes
L. Zunino, D. G. Perez, M. Garavaglia +1
We compare two different definitions for the wavelet entropy associated to stochastic processes. The first one, the Normalized Total Wavelet Entropy (NTWS) family [Phys. Rev. E 57…
Wavelet entropy and fractional Brownian motion time series
Dario G. Perez, Luciano Zunino, Mario Garavaglia +1
We study the functional link between the Hurst parameter and the Normalized Total Wavelet Entropy when analyzing fractional Brownian motion (fBm) time series--these series are synt…
Characterization of laser propagation through turbulent media by quantifiers based on the wavelet transform: dynamic study
Luciano Zunino, Dario G. Perez, Mario Garavaglia +1
We analyze, within the wavelet theory framework, the wandering over a screen of the centroid of a laser beam after it has propagated through a time-changing laboratory-generated tu…
