Abstract: Improved adaptive optical device and associated manufacturing process. The invention relates to an adaptive optical system comprising: a deformable primary plate having an optical surface for deforming an incident wavefront, a plurality of primary actuators for applying a force to said primary plate in order to deform said optical surface, a structure that is fixed with respect to said primary plate, the device also comprising: a deformable secondary plate bearing the primary actuators, a secondary actuator, connected to the structure, and designed to exert, on said secondary plate, a force in an actuation secondary direction in order to deform it, said secondary direction and said secondary plate being secant. The invention is particularly suitable for rapidly and precisely change, with various amplitudes, the curvature of an optical surface intended to modify an incident wavefront within an optical system.

Abstract: The invention concerns an adaptive optical device (I) comprising a deformable plate (2) intended to deform an incident wavefront by refraction and/or reflection, characterised in that it comprises: —tabs (5) fixedly attached to the plate (2), —a frame (21) fixed relative to the plate (2), each tab (5) comprising a moving portion (22) connected to at least one respective peripheral actuator (7) in order that the latter can locally deform the tab (5) in order that the tab transmits a deformation force to the deformable plate (2), each tab (5) further comprising a respective fixed portion (23) fixedly attached to the frame (21) in order to be immobilised relative to the frame. The invention is particularly suitable for the introduction or controlled correction of an optical aberration in an incident wavefront.
