    摘要: A method and device for measurement of the geometrical or optical structure of an optical component such as a lens or a mold for making lens are provided. The method comprises the steps of illuminating the optical component to be measured with incident light having a known wavefront, measuring, in a given plane, the maps of the wavefront slopes of the light, after reflection at or transmission by the optical component, and deducing the surface topography or refraction index map of the optical component to be measured from the measurements of the slope maps by the application of at least one calculating procedure.The calculating procedure comprises a step in which a result surface is initialized using a simple starting surface SD' and at least one optimization step; each optimization step involves calculation of the value of a merit function representative of the departure between the result surface and the surface to be measured of the optical component and, minimization of said value varying said result surface, said variation being expressed in the form of at least one intermediate surface S.sub.i.

    摘要: To determine the focal power of an ophthalmic lens, a plurality of light rays are passed through the lens and a photosensitive position sensor is disposed on the exit side of the lens to measure the coordinates of the points at which the light beams impinge on an analysis plane perpendicular to the lens axis. The light rays comprise three light rays on a circle and a light ray on the system axis.
