Abstract

<abstract abstract-type="main"> <title>SUMMARY</title> <p>Our research team has developed a confocal optical system using a near‐infrared laser that is capable of reducing the effects of scattering when measuring 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 a basic experiment involving measuring blood samples and predicting glucose concentration levels. The results show a high correlation between the glucose concentration and near‐infrared light absorption. We also demonstrate the potential for calculating glucose concentrations in living organisms using our system.</p> </abstract>
