Claim 11:
12. An automatic system for measuring geometric curvature deviations between the dished surfaces of a plurality of materials to be assessed and a dished surface of a reference material, said system comprising an assembly formed by
at least one automatic displacement system comprising a movable arm adapted to travel along at least one trajectory defined along dished surfaces, and
at least one optical contactless detection system adapted to measure a relief height or curvature of dished surfaces, disposed on the automatic displacement system and synchronized with the movements of said automatic displacement system;
said system being configured to:
measure, at selected measurement points along a defined trajectory, the relief height or curvature profile of the dished surface of the reference material, and
measure the relief height or curvature profile of the dished surface of each material to be assessed, at the same selected measurement points along the same trajectory, in the same conditions of travel along said trajectory by the automatic displacement system and according to a same angle of acquisition by the optical contactless detection system at the same measurement point as for the dished surface of the reference material.
