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.
