Abstract
Tatarski has found the frequency spectra for the amplitude, phase, and phase-difference fluctuations of an infinite plane wave propagating through turbulence. Many practical optical beams, used in atmospheric studies, closely resemble point sources, for which the spherical-wave theory is more applicable. The same spectra, calculated for spherical waves, reveal contributions at higher frequencies for amplitude scintillations, nearly identical phase results, and a phase-difference spectrum with no nulls, in contrast with the plane-wave results. Comparison with recent data is shown.

- The phase fluctuations, because they are most sensitive to the largest turbulent eddy scales, have an undefined spatial covariance function for a Kolmogorov spectrum of turbulence. Therefore, the phase power spectrum should be defined in terms of structure functions (Ref. 1) that are less sensitive to large scale variations. The two definitions give the same spectrum when the covariance function exists.
