In the field of wide field or wide angle optical systems, an optical system comprises at least a first optical element and a second adaptive optical element comprising at least one active component, capable of modifying an optical wavefront virtually instantaneously according to a predetermined law, said optical device being designed to produce an image of an illuminated object whose geometric and photometric characteristics are known, the object and the image being at a finite distance or at infinity. The object is decomposed into a plurality of adjacent regions and the active component is arranged in such a manner that, to each region of the object there corresponds at least one predetermined law for modification of the wavefront received by the active component in such a manner that the geometric aberrations of the optical system for said region of the object are minimized. |
