Abstract

A new era of pollution requires an important focus on the conservation of archaeological sites and monuments. During the last decades, there has been a rising interest in the development of sensors based on optical fibers for several applications, including chemical sensing [1]. An innovative new fiber optic sensor that combines Fiber Bragg Gratings (FBG) coated with pH responsive polymers for monitoring the pH of the rains on critical and prestigious monuments is proposed. In this study, the setup arrangement of the optical sensor is modeled by our own FEM code. Monitoring the pH of the water can be used by experts to predict and control the corrosion phenomenon of specific materials, especially limestone and marble, and thus scheduling the timely restoration.
