AB  - Problem statement: Monitoring technique on glucose is a hot topic as this compound has been considered to be important in human healthties. Optical reflectometry has been used to study various concentrations of glucose dissolved in the water. Approach: The self-construction of reflectometer used was of hemi-cylinder aluminum to allow light beam strikes the sample at 70° for sor p-polarization state. The cell for sample was of a hemisphere cavity introduced in the hemi-cylinder face down the surface of stage. The visible light was used as a light source, meanwhile dark Nilon material for a stage has been used to allow the specular reflection by the interface introduced between the liquid sample and the stage. Results: From the investigation, the change of concentrations could be observed from the sensitive change of reflected intensities as indicated by a shift of peak wavelength. Conclusion: The measurement results obtained from a simple set up was encouraging for glucose concentration monitoring for wide applications.
