Paper Abstract

We present the latest concept of the multi-conjugate adaptive optics system for the 1.5-meter solar telescope Gregor. This system will employ three deformable mirrors in order to compensate for seeing introduced by the ground layer, and by shear winds in 5 and 15 km above the telescope ground. Thus, the compensated field of view will grow compared to ground layer compensation only. We describe the design and the used components and present a testbed which is used to improve control algorithms and to test all the components before installing them at the Gregor telescope.
