Abstract

The present disclosure describes an apparatus including a composite panel. The apparatus includes a first composite panel including a first optical fiber embedded therein, the first optical fiber being arranged in a pattern, and a first input port connected to a first end of the first optical fiber, the first input port configured to receive an optical signal from an optical time domain reflectometer. The optical time domain reflectometer is configured to send the optical signal through the first input port and measure a strength of a reflected optical signal that is reflected back from the first optical fiber, wherein the strength indicates a measured optical impedance of the first optical fiber. A measured optical impedance that is substantially the same as a baseline optical impedance for the fiber indicates no damage, while a measured optical impedance that differs from the baseline optical impedance by a predetermined threshold indicates damage.
