Thick optical element having a variable curvature |
摘要 |
The optical element comprises a first bimorph structure, at least one of the components of which is made from piezoelectric material and supply electrodes for the bimorph structure. The element further comprises at least one reinforcing piezoelectric bimorph structure provided with supply electrodes. The latter are respectively connected to the electrodes of the first bimorph structure. An element of the reinforcing bimorph structure is placed against a corresponding element of the first bimorph structure and fixed thereto by a layer of an elastic material. The latter has a tensile strength which is low relative to that of the elements constituting the bimorph structures of piezoelectric material.
