Abstract

The inner scale plays a critical role in beam scintillation and branch point evolution in optical propagation through atmospheric turbulence. Understanding this parameter, in-situ, during experiments is therefore of great interest. We compare different methods of estimating the inner scale using AFRL’s Small Mobile Atmospheric Sensing Hartmann (SMASH). The investigations are conducted with data collected at Kirtland, AFB in New Mexico along multiple paths varying from weak to strong irradiance fluctuation conditions.
