An optical fibre sensor for sensing the corrosion degree on reinforcement in concrete construction consists of 3 parts: a photoemitting circuit, a photoreceiver circuit and a sensitive optical fiber which is made after its core has been plated with reinforced steel bar membrane.On the core of the optical fibre, the vacuum plated sensitive film can transmit the corrosion information to the light wave which is transporting inside the fibre. In this way, corrosion information can be detected. Researches into the sensibility to corrosion of the reinforced steel film which is on the core of the optical fibre have proved that it is feasible to apply optical fibre sensor technology to monitor the reinforcement corrosion in concrete construction.
