Abstract
La présente invention concerne des procédés de calcul d'un signal Méta KG. Le procédé comprend l'éclairage d'une région d'intérêt (2115) dans un échantillon avec une source de lumière proche infrarouge (NiR) et/ou une source de lumière visible. La région d'intérêt comprend une partie échantillon et une partie arrière-plan, ayant chacune un ensemble différent de caractéristiques optiques. Des images de la région d'intérêt sont acquises (2125) et traitées pour obtenir des métadonnées (2135) associées aux images acquises. Des signaux Méta KG sont calculés (2145) pour la région d'intérêt et pour l'arrière-plan. Le signal Méta KG pour l'arrière-plan est utilisé pour ajuster le signal Méta KG pour la région d'intérêt pour fournir un signal Méta KG ajusté final pour la région d'intérêt.
