Paper Abstract

This paper presents a two-axis fiber laser vector hydrophone which uses a V-shaped flexed beam to enhance the sensitivity and reduce the dimensions. Theoretical analyses of the sensitivity and frequent response are given. The key parameters that determine the sensitivity and resonant frequency are discussed. The experimental results show an acceleration sensitivity of 39.2 pm/g and 53.2 pm/g at the x, y axis respectively, a resonant frequency of about 310 Hz, and a directivity resolution larger than 20 dB.
