Abstract

The field of view in adaptive optics is limited by a very narrow isoplanatic angle. A number of deformable mirrors, each conjugated to a different atmospheric layer, might provide phase compensation over an extended field. For this a larger volume need be probed using a multitude of guide stars (see review in [Baharav 1994, 95]). Angel [1994] noticed that the search for planets next to bright stars is limited by scintillation. Scintillation is produced by high turbulence [Tatarski 1971]. If so, why not correct it with a deformable mirror conjugate to that turbulence, whose error signal is provided by the same scintillation? [Ribak 1994, 5].
