Modeling turbulent wave-front phase as a fractional Brownian motion: a new approach
Modeling turbulent wave-front phase as a fractional Brownian motion: a new approach
We introduce a new, general formalism to model the turbulent wave-front phase by using fractional Brownian motion processes. Moreover, it extends results to non-Kolmogorov turbulence. In particular, generalized expressions for the Strehl ratio and the angle-of-arrival variance are obtained. These are dependent on the dynamic state of the turbulence.
