Abstract
Optical devices can comprise a deformable mirror and a system for deforming said mirror. A deformation system comprises a first mechanical structure comprising a first surround, one or more electromechanical actuators attached to the first mechanical structure, a second mechanical structure comprising a substantially planar bottom and a second surround, both deformable, the bottom being attached to the first surround, the second surround being attached to the surround of the mirror, a rigid stud being attached to the bottom, substantially planar and centerd on the bottom, the electromechanical actuator or actuators exerting predetermined forces or bending moments on the stud so as to generate a particular distribution of the bending moments on the surround of the mirror, deforming it according to a geometrical form representative or of one or more predetermined geometrical aberrations.
