Abstract

See full text

An apparatus for estimating a concentration of an analyte includes an optical sensor configured to emit light toward an object and receive light reflected from the object; and a processor configured to obtain a ratio of an absorption coefficient to a scattering coefficient based on the received light, obtain a first absorption spectrum of the object based on the obtained ratio, obtain 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 estimate a concentration of an analyte based on the second absorption spectrum.
