We describe two types of adaptive optics systems developed at FGAN-FOM and the progress in their realization during the last year will be presented. The first system is based on classical adaptive optics scheme and is aimed to resolve objects inside the isoplanatic angle of the wavefront sensor. The second system is based on an iterative algorithm and on the evaluation of the quality of the image to correct the wavefront. This last system is intended to resolve extended targets outside the isoplanatic limits. A constructed mobile system will be also introduced as multipurpose system for measuring atmospheric characteristics as well as tracking and resolving point-like sources in the isoplanatic angle. Finally some results of measurements and attempts to correct the centroid movement of the image of an incoherent point source located at 2.5 km distance using the mobile system will be discussed
