Abstract
This paper presents a three axis slim fiber laser vector hydrophone. Using a V-shaped flexed beam as a mass-spring element, the acceleration in the radius direction can induce axial strain in the fiber laser. Theoretical analysis and finite element method are both used to evaluate the sensitivity and frequent response of the hydrophone. The experimental results show an acceleration sensitivity of 53.2 pm/g, 39.2 pm/g and 38.1 pm/g at the x, y, z axis respectively, a resonant frequency of about 310 Hz, and a directivity larger than 30 dB.
