Paper Abstract

A recently developed scheme for closed loop stable control of two deformable mirrors (DMs) for compensation of both amplitude and phase fluctuations is examined. An approximate model describing the two DM system is developed using the Rytov theory. This model is used to evaluate the impact of measurement noise on the performance of the two DM system. The model is also used to evaluate the impact of misregistration on the stability of the two DM system. Wave optical simulation results are used to validate the predictions obtained from the Rytov theory based model.
