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.

使用光纤加速度计记录水声信号

摘要

开发并研究了一种移动式光纤加速度计的原型，其中将放置在光纤马赫曾德尔干涉仪干涉仪臂中的多匝光机械传感器用作敏感元件。在工作点温度漂移的情况下，使用3×3光纤分路器进行无源相位解调可保持稳定的加速度计操作。显示了使用光纤干涉加速度计对弱水声信号的可检测性。
