Abstract: An optical method for characterizing a diffractive surface having a crystal grain structure, including the steps of: a) successively illuminating said surface with a plurality of light beams (Fi) having propagation directions inclined by a same angle Θ; relative to the normal to the surface and of which the projections on the surface form azimuth angle φ{umlaut over (ι)} that are different relative to a reference direction; b) acquiring an image of the surface corresponding to each of the light beams; and c) digitally processing images to obtain at least one item of information on at least one property of the surface chosen from: the grain structure, texture and level of ordering thereof. An optical head (TO) and apparatus for implementing such a method.

Abstract: The invention concerns a method for producing a chromatography-enrichment column, the method comprising the following steps: (a) depositing at least one layer of desired particles, which may be identical or different, and are intended to constitute the stationary phase, in a compact assembly, on the flat surface of a substrate; (b) crosslinking the layer in at least the regions corresponding to the desired shape of the enrichment column to be obtained; (c) impregnating the layer with a light radiation-sensitive material; (d) insolating the layer obtained in step (c) so as to form insolated regions of which the shape corresponds to the desired internal shape of the enrichment column, if the light radiation-sensitive material behaves like a positive resin or to form non-insolated regions of which the shape corresponds to the desired internal shape of the enrichment column if the light radiation-sensitive material behaves like negative resin; and (e) eliminating the light radiation-sensitive material in the zones corresponding to the internal shape of the enrichment column. The invention is used in particular in the field of chemical analysis.
