Abstract

An optical wave propagating through a random medium with a finite inner scale of turbulence can lead to larger values of the scintillation index than observed when the inner scale is vanishingly small. Calculated values of the refractive-index structure parameter $C_n^2$ based on a direct short path measurement of the scintillation index need to be adjusted for nonzero inner scales. Analytic expressions for this correction factor are now available for both plane waves¹ and spherical waves (not yet published).
