Abstract

We demonstrate a novel fiber-optic hydrophone that use a fiber Bragg grating (FBG) as a sensing element. The operation principle is based on the modulation of birefringence of the FBG by high-frequency ultrasound. By measuring the amplitude of the first Stokes parameters of the transmitted light in FBG using a in line polarimeter, the amplitude and frequency of acoustic pressure can be determined. The FBG hydrophone has a linear response to acoustic pressure, and the sensitivity and dynamic range of the sensor are studied.
