Abstract
Our research team has developed a confocal optical system using a near-infrared laser that is capable of reducing the effects of scattering during a measurement of glucose concentration. We have measured the light reflection of our samples and because our system has the depth resolution offered by a confocal optical system it is able to limit the length of the light path and to detect light absorption at each depth level of the samples; thereby restricting the point of measurement. This report details the use of this system for the basic experiment of measuring blood samples and predicting glucose concentration levels. The results show a high correlation between glucose concentration and near-infrared light absorption. Moreover, we have showed the possibility of calculating glucose concentration in living organisms using our system.
