We describe the results of measurements of irradiant statistics of laser scintillation in the atmosphere, made to find the suitable dimension of the receiving aperture needed to obtain values to be compared to the theoretical ones. Five pin photodiodes collected the intensity of laser radiation after a path of 1200 m or 2400 m in conditions of strong scintillation. We found that, in these conditions, the aperture needs to be not larger than 0.5 mm, better 0.2 mm, in order to correctly measure the second order moment.

Abstract
We describe the results of measurements of irradiant statistics of laser scintillation in the atmosphere, made to find the suitable dimension of the receiving aperture needed to obtain values to be compared to the theoretical ones. Five pin photodiodes collected the intensity of laser radiation after a path of 1200 m or 2400 m in conditions of strong scintillation. We found that, in these conditions, the aperture needs to be not larger than 0.5 mm, better 0.2 mm, in order to correctly measure the second order moment.
