摘要
给出了一种相位调制型Mach—Zender光纤加速度传感器,阐述了该种干涉型光纤加速度计的结构设计及工作原理.通过对该光纤加速度传感系统的力学模型的分析,详细推导出了反映被测信号的加速度与干涉输出的相位差之间的关系表达式,并讨论了决定加速度相位灵敏度的相应参数.
This paper presents a fiber-optic accelerometer based on Mach-Zender phase modulation and expatiates upon the structure design and operational principle of the fiberoptic accelemmeter. Based on the analysis of fiber-optic acceleration sensors, this paper deduces the mathematical relationships between acceleration signal and the output phase difference in detail, and discusses the mechanical model, and related parameters of acceleration phase sensitivity.
