Abstract

In this paper, the set-up of a multi-mode fiber optic sensor for measuring glucose in aqueous solutions is investigated and evaluated. The basis of this sensor is based on the Fresnel Reflection. In this setup, a helium-neon laser is used as a light source, a fiber optic probe, photocell as detector and a digital multimeter. The statistical analysis of the recorded data shows a highly linear behavior in the range of 2 to 25 mM in the glucose solution. The sensitivity and detection limit of this fiber optic sensor are 11.4 mV/mM and 2.5 mM, respectively.
