Paper Abstract

A complex setup intended to fully and accurately measure the influence of the atmospheric turbulence on a near-IR laser beam propagating between two islands of the Spanish Canaries is presented. A measurement campaign was held on this site with the equipment presented. The main parameters under consideration are: far-field pattern, beam spreading, beam wandering, wavefront distortion, atmospheric transmission at the relevant wavelengths, scintillations, and angle of arrival fluctuations. Part of the acquired data is presented, with a preliminary analysis demonstrating agreement with previous data and theoretical predictions. The results confirm the transmission and turbulence levels expected over the propagation path. The use of a fast miniature CCD matrix for the acquisition of turbulence effects on beam propagation is demonstrated.
