ABSTRACT
Non-invasive (NI) blood glucose measurement is a new method, this article deals with current researches and analyzes the advantages and shortages of different measurement methods, including electrochemical process and Optical methods (transmission, polarimetry and back scattering). Then, the technology of near-infrared spectra is emphasized in the analysis. Finally, the problem and technical analysis of non-invasive (NI) blood glucose measurement at the present time are discussed. We preliminarily aim at the method of NI blood glucose determination and the original concept of measuring apparatus, including the choice of incident light wavelength, determination of receiver point, establishment of the optical model of biological tissue, and apparatus design.
