Abstract

Procédé et dispositif de spectrophotométrie différentielle de milieux non limpides par imagerie spectro-temporelle en mode comptage. Selon l'invention, pour analyser un milieu non limpide (11), on éclaire ce milieu par au moins une impulsion lumineuse, on acquiert, à partir du milieu ainsi éclairé, une image spectrale et temporelle de transmission, en mode comptage, et l'on traite l'image et ses dérivées pour acquérir des informations sur le milieu non limpide. L'invention s'applique à l'analyse de milieux diffusants et absorbants, par exemple le lait.
