Closed loop performance of a layer-oriented multi-conjugate adaptive optics system

The dynamic properties of a layer-oriented multi-conjugate adaptive optics system are examined. It is shown that such a system is stable and closes the loop. A simplified analysis of the achievable correction is presented, in order to define the conditions in which the layer-oriented approach is equivalent to other linear reconstruction schemes. It is found that this approach is equivalent to an optimum one, under certain assumptions, but still retaining the potential advantages of such a novel scheme.
