Resumen:
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 turbulence. Following a previous work two quantifiers are used, the Hurst parameter, H, and the Normalized Total Wavelet Entropy, NTWS. The temporal evolution of both quantifiers, obtained from the laser spot data stream, is studied and compared. Finally, the evolution of them allows us to extract information of the stochastic process associated to the turbulence dynamics.
