APPAREIL DE MESURE DE SPECTRE, PROCÉDÉ DE CORRECTION DE LA VARIATION DE TEMPÉRATURE D'UNE SOURCE LUMINEUSE DANS LE SPECTRE, APPAREIL ET PROCÉDÉ PERMETTANT D'ESTIMER LA CONCENTRATION D'ANALYTES

摘要

An apparatus for measuring a spectrum includes a light source array configured to emit light towards an object, a photodetector configured to detect light reflected by the object; and a processor configured to measure, using the light source array and the photodetector, a plurality of temperature correction spectra based on a temperature change of the light source array, obtain a light source temperature drift vector by analyzing the measured plurality of temperature correction spectra, measure, using the light source array and the photodetector, an analysis spectrum by using the light source array and the photodetector, and adjust the measured analysis spectrum to reduce an effect of the temperature change of the light source array by using the obtained light source temperature drift vector.
