The method and device serve to measure a proportion of constituents in blood. To this end, electromagnetic radiation of different radiation wavelengths is directed through a tissue (9) containing blood vessels (1). At least a portion of the radiation exiting the vessel is detected using sensors, and a corresponding measured value derived therefrom is fed to an evaluating device. The evaluating device (10) is connected to at least two sensors (2, 3, 4) and has an analyzer (11) for determining a dispersion of radiation by evaluating the intensity of the radiation received by the individual sensors. An individual calibration determination is carried out by evaluating the angle- dependent dispersion and can be drawn upon for conducting a pulse spectroscopic determination of concentrations of substances.

L'invention concerne un procédé et un dispositif de mesure d'une teneur de certains constituants dans le sang. Des rayonnements électromagnétiques présentant diverses longueurs d'ondes sont guidés au travers d'un tissu (9) contenant des vaisseaux sanguins (1). Au moins une partie des rayonnements sortant des vaisseaux est détectée au moyen de capteurs, et une valeur de mesure déduite correspondante est alimentée à une unité d'évaluation. Ladite unité d'évaluation (10) est reliée à au moins deux capteurs (2, 3, 4) et comporte un analyseur (11) destiné à déterminer une diffusion des rayonnements par évaluation de l'intensité de réception au niveau des capteurs individuels. L'évaluation de la diffusion dépendant de l'angle permet de mettre en oeuvre une détermination de calibrage individuelle pouvant servir à la détermination de concentrations de substances par spectroscopie d'impulsions.
