Abstract

Des aspects concernent la compensation en ligne de dérives instrumentales dans des spectromètres miniaturisés en raison de variations de conditions environnementales et d'autres sources de dérive instrumentale. Le spectromètre peut comprendre un modulateur de lumière, un détecteur et un processeur. Le spectromètre peut en outre comprendre un capteur configuré pour obtenir une valeur d'une condition contribuant à des dérives instrumentales dans le spectromètre. Le processeur peut être configuré pour extraire un ensemble de paramètres de correction d'une matrice de correction associant une pluralité d'ensembles de paramètres de correction à des valeurs de capteur sur la base de la valeur et pour appliquer l'ensemble de paramètres de correction à une sortie du détecteur en vue de produire un spectre corrigé d'un échantillon testé. La matrice de correction peut être générée pour le spectromètre ou peut être basée sur une matrice de correction globale adaptée au spectromètre.
