干涉型光纤加速度传感器综合指标的分析与设计

Analyse and Design on Synthetic Specification of Interferometric Fibre-optic Accelerometer

分析了心轴式光纤加速度传感器的相位灵敏度、频率范围与系统结构参数的联系 ,以及相位灵敏度与频率范围相互之间的制约关系。为了描述这类加速度计的综合指标对结构参数的依赖关系 ,特别引入了一个重要参数——指标容量。分析研究所得到的结论 ,对这类加速度计的设计。

In this paper,the relation among the phase sensitivity,frequency range and system construction parameters of a mandrel type interferometric fiber optic accelerometer is analyzed The restrictive relation between the phase sensitivity and the frequency range is also investigated In order to describe the relation between the synthetic specification of the accelerometer and the construction parameters,an important parameter specification capacity is introduced The conclusions derived from analyses are important for design,analysis and assessment of accelerometers
