1. An apparatus for measuring blood glucose level, comprising:
a light source configured to irradiate light to a subject;
a prism that disperses the light reflected and scattered by the subject for a plurality of wavelength components;
a light receiver configured to detect a spectrum of the light dispersed by the prism and generates electrical signals based on the spectrum of the light; and
a processor configured to extract information on the blood glucose level of the subject based on a Raman shift of the light,
wherein the information on the blood glucose level is extracted based on each of at least three areas of peaks in the spectrum (i) between 1089 cm−1 and 1160 cm−1, (ii) between 1115 cm−1 and 1140 cm−1, and (iii) between 1120 cm−1 and 1130 cm−1.
