Abstract:
1. A non-invasive measurement system for determining ratios of concentrations of at least two analytes of a sample, the system comprising: a light source configured to provide an output spectrum which excites the at least two analytes; receiving optics positioned relative to the light source so as to capture fluoresced light emitted by the at least two analytes upon excitation by the light source; a spectrometric assembly capable of performing quantitative measurements of intensity and wavelength of the fluoresced light emitted by the at least two analytes upon excitation by the light source, wherein the input of the spectrometric assembly is connected to the output of the receiving optics; and a computer system linked to the spectrometric assembly, the computer system comprising computer readable code for computing and providing as output the ratio of the concentration of one analyte relative to the concentration of at least another analyte.
