Representative wavelength determination/investigation in the near infrared region for optical measuring of the human blood glucose

In this study, the phantom mediums which has different optical characteristic were made for detecting of glucose level, then the transmittance based measurements were done. It was studied between 900–2500 nm wavelength which includes higher absorption bands of glucose. An index parameter was improved and used a windowing based method for determining the glucose amount. The correlation was searched between the acquired index parameter and glucose concentrations, and a sensitive wavelength was found for glucose estimation. From the results, 1322–1338 nm were found meaningful for this purpose. In addition, 2144–2165 nm are also found alternative or supplemental wavelengths.
