Features of optical image jitter in a random medium with a finite outer scale

For more than 40 years, we have studied the effect of the low-frequency spectral range of atmospheric turbulence on optical characteristics. We also have looked at the influence of the turbulence models as well as an outer scale of turbulence on the parameters of telescopes and systems of laser beam formations. This question is important mainly for ground-based astronomy. Here we propose what we believe is a new optical method that uses the phase fluctuations of optical image jitter to estimate both the integral (along an atmospheric path) value of the structure parameter of atmospheric turbulence and effective outer scales of turbulence.
