Title (EN) METHOD AND SYSTEM FOR RECONSTITUTING COLOUR INFORMATION OF A SAMPLE MEASURED BY WHITE LIGHT OPTICAL PROFILOMETRY, AND APPLICATIONS OF SAID METHOD
(FR) PROCEDE ET SYSTEME POUR RECONSTITUER UNE INFORMATION DE COULEUR D'UN ECHANTILLON MESURE PAR PROFILOMETRIE OPTIQUE EN LUMIERE BLANCHE, ET APPLICATIONS DE CE PROCEDE
Abstract:
(EN) The invention relates to a method for reconstituting colour information of a sample measured by white light optical profilometry, comprising an acquisition (21) of interferograms at a plurality of points or pixels of said sample, said method also comprising, for at least one measurement point: - calculating (22) the optical spectral density of the interferogram, - determining a spectral reflectance from said optical spectral density, and - processing (24) said spectral reflectance to generate colour information of said sample (17).
(FR) Procédé pour reconstituer une information de couleur d'un échantillon mesuré par profilométrie optique en lumière blanche, comprenant une acquisition (21) d'interférogrammes en une pluralité de points ou pixels dudit échantillon, ce procédé comprenant en outre, pour au moins un point de mesure: - un calcul (22) de densité spectrale optique de l'interférogramme, - à partir de cette densité spectrale optique, une détermination d'une réflectance spectrale, - un traitement (24) de ladite réflectance spectrale pour générer une information de couleur dudit échantillon (17).
