Abstract
Analytical expressions of the temporal power spectral models of angle of arrival (AOA) fluctuations
are derived using the generalized exponential spectral model for optical waves propagating through weak
non-Kolmogorov turbulence. Compared with expressions of temporal power spectral models derived from the
general non-Kolmogorov spectral model, the new expressions consider the influences of the inner and outer
scales of finite turbulence. Numerical calculations show that large outer scales of turbulence increase the
value of the temporal power spectrum of AOA fluctuations in low-frequency regions.
