Kamenev O.T., Petrov Y.S., Podlesnykh A.A., Kolchinskiy V.A., Zavestovskaya I.N., Kulchin Y.N., Romashko R.V. Hydroacoustic Pressure Gradient Recording by a System of Two Fiber-Optic Accelerometers // Bulletin of the Lebedev Physics Institute. - 2021. - V 48 (5). - Page 135 - 138.
The paper presents the results of experimental studies of a portable measuring system based on two inertial fiber-optic accelerometers with a multiturn optomechanical transducer placed in a Mach—Zehnder fiber-optic interferometer arm used as a sensitive element. Passive phase demodulation using a fiber-optic splitter 3 × 3 makes it possible to record interferometer output signals in the presence of a thermal drift of the operating point. The possibility of recording using such an acoustic and hydroacoustic pressure gradient system is shown.
