Abstract

AO optimal control relies centrally on a stochastic model of the turbulence. Models based on both Cn2 spatial priors and temporal dynamics have been used for LQG control for both SCAO and MOAO systems. In this work, we propose turbulence models that account for both wind norm and direction, combining a wind direction-dependent displacement operator with the "boiling turbulence" assumption. We define two extrapolation strategies to complete this new model, and we compare their performance with the LQG control based solely on wind norm priors, through frozen flow simulations. Finally, we discuss about the application of this formalism to WFAO systems.
