Claim 16:
17. A method of calibrating an apparatus for estimating a concentration of an analyte, the method comprising:
emitting light toward an object and receiving light reflected from the object;
obtaining a ratio of an absorption coefficient to a scattering coefficient based on the received light;
obtaining a first absorption spectrum of the object from the obtained ratio of the absorption coefficient to the scattering coefficient;
generating a plurality of candidate scattering correction models by varying coefficients of a function representing a change in a length of a light path according to a wavelength of the emitted light;
obtaining a plurality of second absorption spectra by using the first absorption spectrum and the plurality of candidate scattering correction models;
estimating a concentration of an analyte for each of the plurality of second absorption spectra; and
selecting a candidate scattering correction model, in which a difference between an estimated concentration and an actual concentration of the analyte is minimum, from among the plurality of candidate scattering correction models.
