Abstract
Apparatus and associated methods relate to generating a trigger signal in response to detection of a triggering acoustic event sensed by one of a distributed network of optical acoustic sensors mechanically coupled to an aircraft structure. Each of the optical acoustic sensors is configured to generate an optical response signal indicative of an acoustic condition detected by the optical acoustic sensor. A controller receives the optical response signals and generates, if a triggering one of the optical response signals is indicative of a triggering acoustic event, a trigger signal. The controller also determines a location of the specific one of the distributed network of optical acoustic sensors that generated the triggering one of the optical response signals. In some embodiments, the trigger signal is sent to a Health & Usage Monitoring System configured to perform a health scan, in response to receiving the trigger signal, of the aircraft structure.
