Paper Abstract

The optical transfer function (OTF) is examined for an optical instrument corrected by an adaptive optics systems. A model introducing the application of modal control to the OTF and accounting for the effects of time lags and angular depointings is presented. The model allows the estimation of OTF decay in respect to the Fried diameter and for different time lags in an adaptive mirror. Modal control is described and delays in the controls of the adaptive mirror system are discussed.
