Abstract :
In this paper a very simple refractive index sensor made up of plastic optical fibers is presented. Produced fiber-optic sensor is based on intensity change due to refractive index change. The proposed sensor has linear characteristic in the range of refractive indices of tested liquids (1.33-1.47). The results obtained by simulation are well consistent with the results obtained by measurements and analytically. The proposed sensor is characterized with simple and low-cost design, and high immunity to electromagnetic interference.
