Abstract
A method for determining or designing the topography of at least one unknown surface of an optical element includes the steps of measuring or prescribing geometrical properties, determining a set of integration equations from the geometrical properties, and determining the topography of the at least one unknown surface from the set of equations. The set of integration equations is determined also from the optical index or indexes of the optical element. The geometrical properties measured or prescribed are the geometric properties of a plurality of rays incident upon the optical element and of a corresponding plurality of rays affected by at least the at least one unknown surface.
