Abstract

L’invention concerne un procédé d’étalonnage d’un spectromètre, comprenant : - pour chacun parmi nx canaux de détection du spectromètre et nz configurations expérimentales, détermination d’un rendement de mesure expérimental du spectromètre ; - mise en œuvre d’une étape de calcul (26) comprenant : • une phase (30) d’élaboration de nm modèles ; • pour chacun des nm modèles élaborés, une phase (32) de détermination d’un rendement de mesure simulé de chaque canal de détection ; • pour chacun des nm modèles élaborés, une phase (34) de calcul d’un critère de mérite correspondant ; • pour chacun parmi np paramètres prédéterminés, une phase (36) d’adaptation des grandeurs caractéristiques correspondantes, à partir de la valeur du critère de mérite ; - lorsqu’une condition prédéterminée est remplie, étape (28) de choix d’une valeur étalonnée de chaque paramètre prédéterminé ; nx, nz, np et nm étant des entiers prédéterminés. Figure pour l’abrégé : figure 2The invention relates to a method for calibrating a spectrometer, comprising: - for each of nx detection channels of the spectrometer and nz experimental configurations, determining an experimental measurement efficiency of the spectrometer; - implementation of a calculation step (26) comprising: • a phase (30) for developing nm models; • for each of the nm models developed, a phase (32) for determining a simulated measurement yield of each detection channel; • for each of the nm models developed, a phase (34) for calculating a corresponding merit criterion; • for each of np predetermined parameters, a phase (36) of adaptation of the corresponding characteristic quantities, from the value of the merit criterion; - when a predetermined condition is met, step (28) of choosing a calibrated value of each predetermined parameter; nx, nz, np and nm being predetermined integers.
