Abstract

A prototype of a mobile fiber-optic accelerometer in which a multiturn optomechanical transducer placed in a fiber-optic Mach–Zehnder interferometer interferometer arm is used as a sensitive element is developed and studied. Passive phase demodulation using a fiber-optic splitter 3 × 3 maintains stable accelerometer operation in the case of a temperature drift of an operating point. The detectability of weak hydroacoustic signals using a fiber-optic interferometric accelerometer is shown.
