Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 0:
1. An apparatus for estimating a target component, the apparatus comprising:
a temperature controller configured to modulate temperature of an object;
a measurer configured to measure a spectrum for each temperature of the object that changes based on the modulation; and
a processor configured to:
obtain effective optical pathlength vectors corresponding to a temperature change based on the spectrum for each temperature of the object;
obtain a representative effective optical pathlength based on the obtained effective optical pathlength vectors; and
obtain a target component estimation model based on the obtained representative effective optical pathlength,

wherein the processor is further configured to:
obtain a change in absorbance with respect to the temperature change based on the spectrum corresponding to the temperature change; and
obtain 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.
