MIROIR COMPRENANT DES MOYENS MECANIQUES DE GENERATION D'ABERRATIONS GEOMETRIQUES PRIMAIRES

摘要

The device has a mirror deformation system (S) comprising a first mechanical structure (S1), a first electromechanical actuator attached to the first structure and a second mechanical structure (S2). A planar bottom (Fd) and a surround of the second structure are attached to a surround of the first structure and a surround of a mirror (M), respectively. A rigid stud (P) is attached to the bottom and centred on the bottom. The actuator exerts predetermined force (F3) on the stud perpendicular to a surface of the stud to generate uniform distribution of bending moments on the mirror surround. The mirror deformation system comprises a second electromechanical actuator arranged to exert predetermined bending moment on the stud parallel to the surface of the stud for generating the distribution of the bending moments on the surround of the mirror modulated by a desired trigonometrical function. The mirror is a circular or elliptical plate. The rigid stud is a planar rigid stud. An independent claim is also included for a method for producing a deformable mirror.
