Abstract
An experiment is set up in our laboratory, to measure the enhancement of the lateral displacements, wandering, of a laser beam after a double passage through the atmospheric turbulence. Turbulence is produced by suitable heaters, and a suitable strategy is applied to avoid feedback and to remove noise. Some results are presented that confirm a simple theory developed by us in terms of the geometrical optics approximation.
