Paper Abstract

A novel fiber laser vector hydrophone (FLVH) based on accelerometers is presented. Three fiber laser accelerometers (FLA), perpendicular to each other, are used to detect the acoustic induced particle acceleration. Theoretical analyses of the acoustic sensitivity and the natural frequency are given. Experiment shows a sensitivity of 0.1 pm/Pa@100 Hz is achieved, which results in a minimum detectable acoustic signal of 100 μPa/@Hz@100 Hz. Field demonstration shows that the proposed vector hydrophone has good directivity.
