Query: Characterization of Laser Propagation Through Turbulent Media by
  Quantifiers Based on the Wavelet Transform   The propagation of a laser beam through turbulent media is modeled as a
fractional Brownian motion (fBm). Time series corresponding to the center
position of the laser spot (coordinates x and y) after traveling across air in
turbulent motion, with different strength, are analyzed by the wavelet theory.
Two quantifiers are calculated, the Hurst exponent and the mean Normalized
Total Wavelet Entropy. It is verified that both quantifiers gives complementary
information about the turbulence state.
