摘要

基于光纤干涉的定位系统是一种新型的位置传感器系统

可用于长距离通信干线的定位监测。以往的文献对此系统的输出信号直接作快速傅里叶变换

对外界微扰动信号进行定位。在讨论了系统结构及原理的基础上

提出了一种相位解调算法

用以解决系统对大扰动信号的定位问题

并用软件实现了信号的解调。解调的结果如实地反映了原始扰动信号

保证了定位的精确性。

Abstract

Position determination system based on fiber interferometer is a new position sensor system and can be used as a monitor system in communication main of long distances.Fast Fourier transforming is directly used to the output signals of the system to determine the small disturbances in the former literature.On the basis of the structure and principle of the system

a phase demodulation algorithm is proposed to determine the large disturbances.The signal demodulation technology is realized by software.The results show the output signals are the same as the disturbance signals

and the positions of the disturbances can be determined precisely.
