Romashko R.V., Kulchin Yu.N.,Storozhenko D.V.,Bezruk M.N., Dzyuba V.P. Laser adaptive vector-phase hydroacoustic measuring system // Quantum Electronics. - 2021. - V 51 (3), Page 265 - 271. - March 2021.
We have developed and experimentally implemented an adaptive laser vector-phase hydroacoustic measuring system, which allows one to determine the total acoustic intensity vector. A receiving element of the measuring system comprises six spatially separated fibre-optic coil-type sensors. Signals from the sensors are phase demodulated by using a six-channel adaptive holographic interferometer based on dynamic holograms multiplexed in a photorefractive CdTe crystal. Performance of the developed measuring system has been experimentally tested by determining the bearing and localisation of a source of a weak hydroacoustic field. © 2021 Kvantovaya Elektronika and IOP Publishing Limited.
