Recently, the number of diabetics has steadily increased, and they have to measure their blood glucose level again and again each day. We invented a non-invasive system for measuring blood glucose level based on infrared spectroscopy of attenuated total reflection (ATR). And, using a PLS (partial least squares) calibration model we could measure the blood glucose level of diabetics. The purpose is to examine the accuracy of this monitoring system in clinical trials. And the difference in reflection times of infrared in an ATR prism was examined.
