Fiber-optic microphones for battlefield acoustics.
We describe recent work to evaluate the potential performance of an interferometric fiber-optic microphone for battlefield acoustics. The microphone design has high sensitivity and flat response at low frequency and is readily multiplexed. The design is simple and could be manufactured at low cost, which is desirable since in operation the sensors may need to be disposable. Field trial results from an array of microphones are discussed.
