Abstract :
Luminescent-dye-doped-plastics are nowadays extensively used for esthetic purposes (toys, ballpoint pens, etc.). In the early 1980´s, these materials were investigated to be used as sunlight concentrators in energy generation. Recent developments in fiber optic technology, beyond mere data transmission, lead us to consider the feasibility of using such materials for light intensity sensing in fiber optic sensors networks. The sensor described in this work has proved to show high linearity, reproducibility and stability, and low directivity, however it lacks high sensitivity. Further optimization of some design parameters will definitely help to improve it
