Atmospheric turbulence over vertical paths or long horizontal paths perturbs phase in the pupil of an optical communications receiver, and also can cause severe intensity scintillation. We describe a mathematical method for predicting a bound for these fluctuations by using the Strehl ratio as a criterion for determining the variations in the intensity fluctuations. Derived is the probability function of the instantaneous Strehl ratio, in addition to methods for computing the lower confidence limit. We show how these functions can vary by the degree of partial wavefront correction via adaptive optics.
