Ammonia detection in water with balloon-like plastic optical fiber sensor

This work presents the demonstration of a plastic optical fiber(POF)-based ammonia sensor. The sensor head is formed by bending an unclad fiber optic sensor into a balloon-like structure. The bending radius of the balloon-like bent fiber optic sensor is varied from 1.0 to 2.5 cm. The performance of...
