Abstract:
A system for adjusting a deformable mirror, comprising:a reaction plate; a plurality of pneumatic actuators coupled to said reaction plate; and a plurality of push-pull flexures coupled on a first end to said pneumatic actuators, and coupled on a second end to the non-reflective side of said deformable mirror, said plurality of push-pull flexures being disposed at various locations on the back of said deformable mirror; whereby said coupled push-pull flexures and pneumatic actuators are operated to support and alter the shape of said deformable mirror to allow for correction of a plurality of optical aberrations; and whereby said coupled push-pull flexures and pneumatic actuators are operated in sets, such that zero net force is realized across the boundaries of the deformable mirror.
