Interferometric Method And Instrument For Measurement And Monitoring Blood Glucose Through Measurement Of Tissue Refractive Index (Wo 2008/076228)
A method of measuring glucose concentration in tissue includes measuring scattering coefficients of the tissue at each of a plurality of temperatures and at a selected tissue depth using optical coherence tomography, and determining the glucose concentration in interstitial fluid of the tissue as a function of the measured scattering coefficients.
