Sound source localization based on Michelson fiber optic interferometer array

Abstract Sound source localization is of high attention and importance. Microphone array is one of the most common technologies in acoustic source localization. In this paper, a fiber optic array acoustic sensor based on Michelson interferometer is proposed, which can be applied for sound source localization in hash environments. Sound source localization is realized through this array system. The experiment results show that the array has a high sensitivity, and the localization accuracy can be up to 0.01 m.
