| 摘要 |
The present invention refers to a deformable lens structure for adaptive optics devices. The lens structure comprises: - a first layer (2) elastically deformable in response to an applied force, said first layer having a first outer surface (21), adapted to receive an incident light beam (L), and a first inner surface (22), opposite said first outer surface, at least a first central portion (20) of said first layer being transparent to said light beam (L); a second layer (3) positioned spaced with respect to said first layer, said second layer having a second inner surface (31), facing the first inner surface (22) of said first layer, and a second outer surface (32), opposite said second inner surface, at least a second central portion (30) of said second layer being transparent to said light beam (L); - a shaped spacer element (4), positioned between the first inner surface (22) of said first layer and the second inner surface (31) of said second layer and integrally connected to said first and second layer, and an inner chamber (5) having walls defined by said spacer element (4) and by said first and second layer (2-3), a liquid (6) transparent to said light beam (L) being present in said inner chamber in contact with said first and second layer. - one or more first electrostatic actuators (811, 812, 813, 831, 832) transparent to said light beam (L), said first electrostatic actuators being operatively associated with said first layer and positioned at the first central portion (20) of said first layer; one or more second electrostatic actuators (821, 822, 823, 841, 842) transparent to said light beam (L), said second electrostatic actuators being operatively associated with said second layer and positioned at the second central portion (30) of said second layer. |
