Paper Abstract

New analytical models of the spatial power spectra of temperature fluctuations and refractive-index fluctuations in the atmospheric boundary layer, showing the characteristic "bump" just prior to the dissipation ranges, have recently been developed as a modification of the standard Tatarski model. Using this new model for the power spectrum of the refractive index, new expressions are developed for the phase structure function of an optical wave propagating through atmospheric turbulence. The effects of this new phase structure function on the phase coherence length, and hence on Fried's seeing parameter r0 for the critical diameter of a telescope, are also examined.
