This paper presents a novel hexapod as the adjustment mechanism for a telescope to actively align its secondary mirror. The special hexapod provides six degrees of freedom (6-DOFs) with decoupled translation and rotation. The decoupled kinematic motions are analyzed and commented on as the alignment...
