Adaptive Optics
Submitted by zennaro2 on
Adaptive optics (AO) is used in astronomy to obtain high resolution images, close to diffraction limited, of stars and galaxies with ground telescopes, otherwise blurred by atmospheric turbulence.In order to succesfully compensate for the distorsion induced by athmospheric turbulence one (or more) deformable mirros are deformed; the control action used measurements of the wavefront distorsion.Next generation AO systems have thousand of sensors and actuators and as such pose non-trivial issues both for modeling and control.In this respect, it is important to predict the turbulent phase affec
