Abstract

Procédé de mesure interférométrique relatif à la surface. Un faisceau 5 de lumière cohérente collimatée est dirigée sur un réseau 9 en partie directement 7 et en partie par réflexion 8 sur la surface de l'objet à mesurer 10. Les angles d'incidence et l'angle entre le réseau et la surface de l'objet sont choisis tels que chacun des faisceaux incidents sur le réseau a un ordre de diffraction parallèle à l'ordre de diffraction de l'autre faisceau. Le dispositif utilise comme plan de référence les fronts des ondes lumineuses. La distance entre l'objet et le réseau peut être grande de 5 à 50 cm. Peut être utilisé pour mesurer des éléments de surface même substantiellement non réfléchissante.
