Abstract
A new method is proposed for the verification of the atmospheric
turbulence model. It is based on the reconstruction of the phase structure function from
simultaneous measurements of the Angle-of-Arrival longitudinal
covariance at different baselines with the Generalized Seeing Monitor (GSM). In addition, with
this new technique we obtain the first non-model dependent estimates of the outer scale with the GSM.
Preliminary results of the reconstructed phase structure function with this technique are presented and
compared to those obtained theoretically with the most known atmospheric turbulence models.
