1. A method for collecting optical data, the method comprising:

  • propagating light from a source of light to a detector of light to produce a measured reference spectral distribution by interaction of the light with a reference sample;

    propagating light from the source of light to the detector of light to produce a measured subject spectral distribution by interaction of the light with a subject sample;

    identifying at least one of an intensity change and a wavelength shift between the measured reference spectral distribution and a stored reference spectral distribution; and

    comparing the measured subject spectral distribution and its associated stored reference spectral distribution with a stored subject spectral distribution and its associated stored reference spectral distribution, wherein such comparing includes accounting for the identified one of the intensity change and the wavelength shift.
