Paper Abstract
Extensive attention has been paid to optical fiber microphone because of its especial merits, such as anti-electromagnetic interference, corrosion resistance, high sensitivity, safety and reliability. In the present study, a kind of optical fiber microphone array based on Sagnac interferometer using a broadband source is proposed. On the basis of the high sound quality and wide bandwidth of optical fiber microphones, the acoustic source localization theory is tested and verified in practice. The results prove the possibility of determine the location of acoustic source in a wide range of frequencies accurately. Besides its feasibility, the scientific value and application prospect, such as in battlefield and ultrasonic detection field, are great.
