Claim 11:
12. A method of estimating a target component, the method comprising:
modulating temperature of an object;
obtaining a spectrum for each temperature that changes based on the modulation;
obtaining effective optical pathlength vectors corresponding to a temperature change based on the spectrum for each temperature;
obtaining a representative effective optical pathlength based on the obtained effective optical pathlength vectors; and
obtaining a target component estimation model based on the obtained representative effective optical pathlength,
wherein the obtaining of the effective optical pathlength vectors corresponding to the temperature change comprises:
obtaining a change in absorbance with respect to the temperature change based on the spectrum corresponding to the temperature change, and
obtaining the effective optical pathlength vectors corresponding to the temperature change based on a relationship between the obtained change in absorbance and a change in optical pathlength, a change in absorbance being proportional to a sum of the effective optical pathlength multiplied by the change in an absorption coefficient and the absorption coefficient multiplied by a change in the effective optical pathlength.
