Abstract

Wandering of a laser beam in the atmosphere is due to fluctuations of the refractive index of the atmosphere and, having a strong dependence on the path length, is very useful to investigate random or continuous changes of the refractive index during time. First, we describe methods we developed and applied to locally investigate the parameters of turbulence (inner scale, outer scale and structure constant) based on our previous theory of propagation of "thin" beams. Then we describe use of thin beams to investigate the evolution of the refractive index gradient and show experimental results including non stationary and non isotropic conditions.
