1. A method for calibration of an apparatus for measuring blood glucose level, comprising:
irradiating, by a light source, light to a subject such that the light is output at a predetermined output for a predetermined duration;
generating, by a light receiver, electrical signals representative of a Raman spectrum of the light that is reflected and scattered from the subject; and
determining an intensity and an exposure duration for the light to be irradiated by the light source to subsequently measure the blood glucose level of the subject based on a peak corresponding to a specific Raman shift of the Raman spectrum acquired via the light receiver during the calibration.
