1. A method for non-invasively probing the inner structure of the skin of a patient, comprising:

  • directing an excitation pulse at a region of the patient'"'"'s skin;

    exciting a portion of the patient'"'"'s skin as a result of the excitation pulse at the region to generate a fluorescence signal indicative of the composition of the patient'"'"'s skin;

    detecting the fluorescence signal generated by the excitation pulse;

    measuring an intensity decay of the fluorescence signal as a function of time to detect development of a metabolic disease affecting the patient;

    measuring the reflectance of the excitation pulse;

    measuring the transmittance of the excitation pulse; and

    wherein the transmittance, reflectance, and time-resolved fluorescence measurements are performed simultaneously;

    wherein the transmittance, reflectance, and time-resolved fluorescence measurements are calculated using an inverse marching method.
