Abstract:
1. A device for correcting at least one optical aberration, of known evolution of an optical system, the device comprising: a deformable mirror having a contour and geometry selected such that the contour of the mirror is defined from a composite function of said at least one optical aberration to be corrected; an intermediate plate having a contour identical to that of the mirror; a single actuator, placed under the intermediate plate and configured to apply a force F of a given intensity in the centre of an under part of the intermediate plate; a ring placed above the intermediate plate, the mirror being placed on the ring; wherein the intermediate plate is connected to the deformable mirror by the ring, said intermediate plate being configured for applying via the ring a flexing moment on an edge of the mirror, the deformable mirror being concave or convex when it is deformed, wherein the composite function is defined in a position in cylindrical coordinates F with z the deformation of the optical surface, (ρ,θ) the coordinates in the polar position and a
