Monitoring of Various Glucose Concentrations Based on Optical Spectroscopic Reflectometry

Variation of glucose's concentrations have been monitored their different optical properties using a self-construction of a spectroscopic reflectometer. The measurement was done by illuminating the glucose (liquid sample) using a visible light source at an incident angle of 70° for s-polarization state. From the investigation, change of concentrations could be observed from the sensitive change of optical reflected intensities as indicated by a shift of peak wavelength. This phenomenon is encouraging for glucose concentration monitoring for wide applications. [PUBLICATION ABSTRACT]
