Abstract
We report on the measurement of sound pressure in water utilizing the modulation of the optical reflectivity at the end of an optical fiber. First, we develop a new experimental setup comprising a low-coherent light source to suppress the interference noise. Then, we formulate the relation between the sound pressure and the modulation in the reflected light intensity, and theoretically analyze the performance of this method with emphasis on the directivity and the sensitivity.
