【摘要】 分析了一种迈克尔逊干涉型光纤加速度计的结构设计和工作原理,详细推导了被测信号的加速度与迈克尔逊干涉仪的输出相位差之问的关系,并对加速度的灵敏度进行了相应的参数讨论,最后应用Matlab软件对光信号处理电路进行了仿真;结果表明,解调信号和待测信号相位一致性好,从而从理论上证明了这种结构新颖、体积小、精度高、成本低的干涉型光纤加速度计是合理可行的。更多还原

【Abstract】 The principle and design of a fiber -optic accelerometer based on Michelson interferometry are described. Then the mathematical relationships between the acceleration signal and the output phrase are presented in detail, and related parameters are discussed subsequently. Finally, the signal processing system is simulated by Matlab software. The results of simulation show that the signal to be measured and the demodulated signal have a good phase agreement.更多还原
