Abstract
Methods and systems for providing real-time monitoring of a metal surface are provided herein. The system includes a fiber-optic cable disposed alongside a length of a wall that includes the metal surface. A laser source is attached to the fiber-optic cable to transmit light through the fiber-optic cable. An acoustic source is configured to generate acoustic signals in the metal surface, wherein the acoustic signals interact with the fiber-optic cable and influence characteristics of the light. A receiver is attached to the fiber-optic cable to detect the light. The system also includes a signal processing unit configured to determine a location of a change in the metal surface based on changes in the characteristics of the light.
