As a means of managing diabetes, there is a need for a non-invasive glucose component measuring device. In this study, we investigated the possibility of measuring non-invasive glucose components using near-infrared spectroscopy. A measurement experiment was conducted by preparing a glucose component solution from 0% to 25% in 5% increments. The measured data was first represented by a graph of wavelength and optical measurements using Matlab. As a result, there was a section in which the optical measurement value for each concentration was highly reliable according to the wavelength. Thus, we selected a wavelength region with high measurement reliability and graph the glucose concentration and optical measurements using Matlab. As the glucose concentration increases, the absorption tends to increase and the reflectivity tends to decrease, so we find the possibility of measuring the glucose concentration using near-infrared spectroscopy.
