Adaptive optical device and associated manufacturing process

A method for manufacturing an adaptive optical device including at least:

• a primary step of making or providing a deformable primary plate having an optical surface intended for deforming an incident wavefront by refraction and/or reflection,
• a secondary step of making or providing a deformable secondary plate,
• a step of positioning a plurality of primary actuators in such a way, on the one hand, that said plurality of primary actuators can each apply a respective force in a primary direction of actuation to said deformable primary plate in order to deform said optical surface, and on the other hand, that said plurality of primary actuators are supported by said deformable secondary plate,
• a step of positioning at least one secondary actuator in such a way, on the one hand, that said at least one secondary actuator is connected to a frame, which is fixed with respect to said deformable primary plate, and on the other hand, that said at least one secondary actuator can exert, on said deformable secondary plate, a force in a secondary direction of actuation in order to deform said deformable secondary plate, said secondary direction of actuation being secant to a main extension plane of said deformable secondary plate, said deformable primary plate having at least one peripheral surface extending around and/or adjacent to said optical surface, the method further comprising a step of positioning a plurality of external actuators, in such a way that the plurality of external actuators connect the frame and the at least one peripheral surface of the deformable primary plate, the plurality of external actuators being configured to each apply a punctual force on said at least one peripheral surface in order to deform said deformable primary plate, the plurality of external actuators being distinct from said at least one secondary actuator.
