Abstract

This work deals with active correction of the aberrations in a telescope by moving the secondary mirror. A special attention is here dedicated to the case of a secondary mirror whose motions are controlled by a 6-6 Stewart Platform (generally called by astronomers simply "hexapod", even if this term is more general). The kinematics of the device is studied; an iterative algorithm to solve the non trivial forward kinematics problem is described.
