Unclad plastic optical fiber temperature sensor with a balloon-like structure

An unclad plastic optical fiber (POF) temperature sensor with high sensitivity is experimentally demonstrated in this work. The working principle of this developed unclad POF sensor is based on intensity-modulated technique. In general, position and length of the unclad region in this developed s...
