For the purpose on monitoring the condition in the interior of a closed metallic honeycomb panel, an optical fiber is embedded therein. An optical connector, secured within a groove has one end exposed to a source of external light, while the optical fibers are connected to the other end of the connector. In the example disclosed, the end of the optical fiber within the structure is coated with a sensor material subject to the same condition (corrosion) taking place within the structure. The reflectivity of the coating from a source of light applied through an optical connector is a measure of the condition.
