Underwater Acoustic Sensors Based on Fiber Bragg Gratings This limit is essentially due to the high Young module of the optical fiber material (tens of GPa)

More specifically, we study the complex opto-acousto-mechanical interaction among an incident acoustic wave traveling in water, the optical fiber surrounded by the ring-shaped coating, and the FBG inscribed in the fiber, via full-wave numerical simulations by means of a multiphysics software package based on the finite-element method (FEM).

Opto-acoustic coupling-based DCS represents one of the most recent developments, and deserves more attention due to its unique feature, whereby only the standard fibre is needed. Better performance can be expected after a short period of development. An optoacoustic sensor for trace analysis in gases was constructed and experimentally tested.
