Abstract

A 4-element fiber optic hydrophone array based on distributed feedback fiber lasers (DFB FL) has been developed, constructed and tested. Acoustic sensitivity was enhanced by two diaphragms. The noise floor was tested to be 10^-6 pm/√Hz @ 1 kHz and acoustic pressure sensitivity of about 10 nm/MPa was achieved.
