Abstract
A method for detecting a structural fault in a structure includes the steps of, (a) performing a Brillouin measurement at a point along a sensing optical fiber which operably cooperates with the structure, to obtain a Brillouin gain spectrum at that point; (b) identifying at least two curves which, when added together, best fit the Brillouin gain spectrum; (c) identifying if peaks of the least two curves occur at different frequencies so as to determine if the structure has a structural fault. There is further provided a corresponding apparatus for detecting a structural fault in a structure.
