Patent ID: 8876306

Claim:
Optical device comprising at least one deformable mirror and a system for deforming said mirror, said mirror of substantially circular form having a reflecting face and an opposite face comprising a surround attached to the deformation system, wherein the deformation system comprises at least: a first mechanical structure comprising at least one first surround; a first electromechanical actuator 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 attached to the bottom, substantially planar and centered on the bottom, the first electromechanical actuator exerting a predetermined force on the stud perpendicularly to the surface of said stud, so as to generate a uniform distribution of bending moments on the surround of the mirror; and a second electromechanical actuator, said second actuator being arranged so as to exert a predetermined bending moment on the stud parallel to the surface of said stud, so as to generate a distribution of the bending moments on the surround of the mirror modulated by a sine or a cosine function.
