Effect of adaptive telescope mirror dynamics on the residual of
atmospheric turbulence correction

A. Riccardi

INAF - Osservatorio Astrofisico di Arcetri


In the present report we quantify the residual error of the correction of the atmospheric turbulence depending on the dynamical response of an Adaptive Telescope Mirror. The mirror is modeled having modes in closed loop with mass-spring-damper response. The equivalent transfer function is used to filter the atmospheric disturbance power spectrum and obtain the residual error.
