On March 2, 2005, Rolo Cantarutti has successfully closed the AO loop on the SAM prototype in the laboratory. The images show a point source in the closed-loop compensation (left) and with zero voltage on the DM (right). The second image is distorted by imperfect shape of the DM and static aberrations in the system. Only about 20% of the DM dynamic range is used for its self-compensation.
