Abstract

In this paper we inspected which properties the refraction index inherits from the turbulent atmosphere. Because it does not affect the velocity field and evolve under a diffusion equation it is found to be a passive scalar field. So it inherits the stochastic properties of the velocity field. We observed this behavior from the wandering of a laser beam that travels through air in turbulent motion, these deviations are found to be proportional to the refraction index.
