Classification: CPC A  G | IPC A  G

Claim 9:
10. A method of 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;
obtaining a second absorption spectrum by eliminating a scattering correction spectrum from the first absorption spectrum, the scattering correction spectrum corresponding to a nonlinear change in the scattering coefficient according to a wavelength of the emitted light; and
estimating a concentration of an analyte based on the second absorption spectrum,
wherein the scattering correction spectrum is expressed as a function representing a change in a length of a light path according to the wavelength of the emitted light; and
wherein the obtaining the second absorption spectrum comprises obtaining the second absorption spectrum by using a scattering correction model based on the function.
