摘要：

A new fiber optic hydrophone is described. based on a distributed feedback fiber laser (DFB-fiber laser) Experimental arrangement consists of DFB-FL, unbalanced Mach-Zehnder interferometer, piezoelectric (PZT) modulator, detection and feedback control circuit, and oscillograph. Experimental results show that the bare DFB-FL hydrophone is extremely sensitive to small perturbations in their environment and can acquire exact acoustic signals. © 2007 Tianjin University of Technology.
