The present study aims to propose a corrosion detection method using a optical fiber sensor coated with a thin iron film. To evaluate the detection accuracy using the proposed method, 2 typed iron film with thicknesses of 100, 200 nm were used to monitor the reflectivity from corroded iron film via light source injection and the measurement was conducted in air, salt water, mortar packed conditions. As a result, it was found that the thickness of iron film is more sensitive to change in the reflectivity than the variation of exposure conditions
