Abstract

A compact 2-D deformable mirror is proposed which consists of multiple electrostrictive laminar sheets bonded to the backside of a mirror glass plate. A set of desired wave fronts is considered; the sheets are assigned to generate each wave front separately. The electrode of each sheet is designed so that the exact voltage distribution required to deform the mirror surface is approximated optimally by a few discrete voltages. In actual operation, the deformation of the mirror is determined by the superposition of properly weighted contributions from all the actuators. The usefulness of the construction is demonstrated experimentally.
