1. A method of characterizing a patient'"'"'s blood glucose concentrations based on optical coherence tomography, the method comprising:

  • employing optical coherence tomography to measure light reflected from a patient'"'"'s skin tissue at a plurality of depths;

    determining a tissue scattering coefficient for a tissue region based on differences in light reflected at different depths;

    detecting micro-oscillations in the tissue scattering coefficient over a time interval; and

    relating the micro-oscillations to the patient'"'"'s blood glucose concentrations.
