Popis:	The spatial scale of variations of intensity imposed on a propagating beam as it transits the turbulent atmosphere is of importance in designing free space laser communications receivers. Consecutive images of the entrance pupil of a 125mm diameter telescope have been acquired at a rate of 328fps over a series of ranges from 2km to 24km. The images are analyzed with respect to the aperture averaging available to a given receiver system.
