Abstract
A non-invasive glucose concentration measurement apparatus includes: a light source which projects at the sample radiation of a wavelength range including a wavelength at which absorption greatly changes with glucose concentration but does not greatly vary with temperature; a photosensor which receives the radiation which have been projected by the light source, and transmitted through or reflected by the sample, and generates an electrical signal corresponding to a through-transmitted or reflected level of the radiation of the wavelength; and a calculator which calculates a glucose concentration based on the electrical signal. A more accurate glucose concentration can be obtained without the influence of temperature.
