SYSTEM FOR THE DETERMINATION OF THE SURFACE AND MECHANICAL CHARACTERISTICS OF FILAMENTARY STRUCTURES, IN PARTICULAR SKIN APPENDAGES, STRUCTURES ASSOCIATED THEREWITH, NATURAL OR SYNTHETIC FIBERS AND THEIR AGGREGATES

摘要

A system is described for the characterization of vital or reconstituted tissues, in particular skin appendages such as hair or eyelashes or structures associated therewith, comprising in combination: a plurality of sources (12) of electromagnetic radiations adapted to be oriented spatially and to irradiate according to a selected angle of incidence a sample (S) of vital or reconstituted tissue comprising a series of filaments of a person which are homogenous in their structural type; at least one image acquisition device (14) adapted to receive a reflected and/or dispersed radiation from the sample (S), or a fluorescence radiation emitted by the sample (S); and an image processing unit (18) designed to process reflection and/or dispersion images and/or fluorescence images, and to classify the tissue being examined in order to compare the value of at least one out of the parameters of gloss, dimensions, colour intensity, contour of the filaments of the sample (S) with a database of parameters of classes of predetermined vital or reconstituted tissues, and/or to compare the value of at least one out of the parameters of gloss, dimensions, colour intensity, contour of the filaments of the sample (S) with a database of historic values of parameters of the tissue.
