Abstract

Intrinsic optical fiber microphones with the design that we propose have a good sensitivity and dynamic allowing them to address many innovative applications. But their performances induce some defects as noise sensing that has to be separated to the wanted sound signal to obtain a clean usable sound signal. In this paper we introduce the design of an optical fiber sound sensing system and the bases of the adapted signal processing allowing to use all the advantages of this design with a low level of noise. The results are very promising.
