Paper Abstract

In this paper, we developed and investigated an adaptive fiber-optic hydrophone based on adaptive holographic interferometer which key element is dynamic hologram recorded in a photorefractive crystal of cubic symmetry in orthogonal geometry. Different modifications of primary fiber-optic receivers of acoustic pressure are designed and studied. The adaptive hydrophone provides high sensitivity to acoustic pressure (up to 8.6 mV/Pa) and high level of immunity to all kind of noisy instabilities of environment.
