Paper Abstract
The demand for highly sensitive and reliable sensors to assess the refractive index of liquid get many applications in
chemical and biomedical areas. Indeed, the physical parameters such as concentration, pressure and density, etc., can be
found using the refractive index of liquid. In contrast to the conventional refractometer for measurement, optical fiber
sensor has several advantages like remote sensing, small in size, low cost, immune to EMI etc., In this paper we have
discussed determination of refractive index of sugar solution using optical fiber. An intensity modulated low cost plastic
fiber optic refractive index sensor has been designed for the study. The sensor is based on principle of change in angle
of reflected light caused by refractive index change of the medium surrounding the fiber. The experimental results
obtained for the sugar solution of different refractive indices prove that the fiber optic sensor is cable of measuring the
refractive indices as well as the concentrations.
