    Abstract: The invention relates to a method for absolute measurement of the geometrical or optical structure of an optical component (4), comprising steps consisting in: - illuminating the said optical component with incident light, the wavefront of which is known, - measuring, in a given plane, the maps of the slopes of the wavefront of the said light after reflection from the said optical component or transmission by the said optical component, which furthermore comprises at least one calculation procedure consisting in deducing the geometrical or optical structure of the optical component from the said measurement of the slope maps. A further subject of the invention is a device for implementing this method. The invention is applied in particular in the field of ophthalmology for checking or measuring ophthalmic lenses or moulds for fabricating ophthalmic lenses.

    Abstract: L'invention concerne un procédé d'impression d'un motif par jet d'encre sur une surface, comprenant les étapes suivantes : (a) déposer sur au moins une partie de ladite surface une première couche d'encre comprenant des gouttes d'encre E1, par éjection au moyen d'une tête d'impression à une première vitesse d'éjection V1 de gouttes d'encre E1 ayant un premier volume VOL1, et (b) déposer sur au moins une partie de ladite première couche d'encre au moins une deuxième couche d'encre comprenant des gouttes d'encre E2 ayant un second volume VOL2, par éjection au moyen d'une tête d'impression à une vitesse d'éjection V2 de gouttes d'encre E2. La première vitesse V1 est supérieure à la seconde vitesse V2 et le second volume VOL2 des secondes gouttes d'encre E2 est supérieur au premier volume VOL1 des premières gouttes d'encre E1.
