The health monitoring of engineering infrastructure has received more and more extensive attention. Steel corrosion is known as one of the major structural defects for steel structures such as pipes and plates. The corrosion can be monitored by detecting the change in color. The plastic optic fiber (POF) can detect the color and has the ability to provide real-time monitoring. Therefore, the POF sensor could be a potential candidate for steel corrosion detection. In this article, a corrosion detection approach is developed using POF sensors. The sensing principle and laboratory accelerated corrosion tests are discussed.
