Abstract (en)
[origin: WO2017129634A1] A method for determining a level of a substance in a material is disclosed. The method comprises: obtaining a first measured spectrum from a first noninvasive sensor, the first measured spectrum relating to a first characteristic of the material; obtaining a second measured spectrum from a second noninvasive sensor, the second measured spectrum relating to a second characteristic of the material; calculating a first intermediate estimate ŷ x of the concentration of a chemical constituent in the material based on the first measured spectrum; calculating a second intermediate estimate ŷ 2 of the concentration of a chemical constituent in the material based on the second measured spectrum; determining a first and second residual spectrum r1, r2, the residual spectra defined as the deviation between the measured spectrum and an estimated spectrum, the estimated spectrum being the component of the measured spectrum corresponding to the intermediate estimate of the concentration of the chemical constituent; and calculating an improved estimated concentration of the chemical constituent in the material based on the first intermediate estimate ŷ 1, the second intermediate estimate ŷ 2 and the residual spectra r1, r2.
