abstract

A new fibre optic hydrophone based on a distributed feedback fibre laser (DFB FL) sensor is described. The sensor is designed to achieve ocean noise limited pressure sensitivity. Unlike previous fibre laser acoustic sensors, this device is acceleration insensitive making it less susceptible to vibrational noise. Experimental results for one implementation of the sensor are presented.
