Abstract

L'invention concerne un procédé non invasif pour la détermination de la concentration d'un analyte à l'aide d'informations spectrales Raman ou de fluorescence. Une bande de lumière de haute intensité est appliquée sur un côté du tissu de la peau. La lumière de haute intensité pénètre dans le tissu cutané et génère un signal Raman ou de fluorescence. Une matière de génération de Raman ou une matière de génération de fluorescence est placée à un endroit aussi proche que possible, de l'autre côté du tissu cutané. La matière de génération de Raman ou de fluorescence est située en général à l'opposé de l'entrée de la lumière de haute intensité appliquée. Le signal Raman ou de fluorescence est recueilli et la concentration d'analyte est déterminée à l'aide du signal Raman collecté.
