  • Adaptive optical device of simplified construction and associated manufacturing method
    Patent number: 11774747
    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.
