Abstract

L'invention concerne une méthode d'analyse non invasive de tissu sous-cutané consistant à irradier une surface du tissu avec un rayonnement infrarouge à ondes courtes (SWIR) dans une première bande spectrale qui est fortement absorbée par l'eau, et avec un SWIR dans une seconde bande spectrale de telle sorte que l'interaction du rayonnement dans les deux bandes spectrales avec un composant du tissu autre que l'eau est sensiblement identique. L'intensité du rayonnement dans chacune des bandes spectrales qui émerge du tissu est mesurée. L'absorption relative par le tissu du rayonnement dans l'une des bandes spectrales par rapport à l'absorption par le tissu du rayonnement dans l'autre des bandes spectrales est calculée. L'état du tissu est déterminé en fonction de l'absorption relative calculée.
