Title
(EN) DEDICATED SPECTRAL ILLUMINATION SPECTROSCOPY
(FR) SPECTROSCOPIE D'ÉCLAIRAGE SPECTRAL SPÉCIAL
Abstract
(EN)
Apparatus and method for an analyte determination in blood, relying on spectroscopic techniques, in which sample is illuminated with light having dedicated spectral characteristics. The first light source (20) is a broadband light source in the IR-range, the second light source (25) is comprised of one or more monochromatic sources, such as laser diodes. The sources are chosen to correspond to wavelength highly correlated with glucose adsorption.

La présente invention concerne un appareil et un procédé destinés à la détection d'un analyte dans le sang, reposant sur des techniques de spectroscopie, dans lesquels un échantillon est éclairé avec une lumière possédant des caractéristiques spectrales spéciales. La première source de lumière (20) est une source de lumière à large bande dans la plage de l'infrarouge et la seconde source de lumière (25) comprend une ou plusieurs sources monochromatiques, telles que des diodes laser. Les sources sont choisies de manière à correspondre à une longueur d'onde sensiblement adaptée à l'adsorption du glucose.
