Abstract
A novel underwater fiber laser vector hydrophone is presented. Theoretical and experimental analyses are carried out to test the performance of the hydrophone, which shows a sensitivity of 25 pm/g and a flat frequency response in the range of 5 Hz~200 Hz are achieved. Field demonstration shows that the vector hydrophone has good directivity.
