| Abstract: | Abstract The dependence of beam wandering (random lateral displacement) on distance of a thin beam propagating through strong indoor turbulence is investigated experimentally. In the case of small fluctuations and within the limits of the geometrical-optics approximation, the transverse displacement variance is expected to follow a third-power law dependence on distance. Here we present the results of measurements made over paths of a few metres, both in the laboratory and in a large corridor. Inner scale measured values are also reported. |
