摘    要:光纤干涉型传感器是由于外界信号作用到干涉仪上,引起干涉信号相位的变化,通过对相位的解调来反应外界信号。介绍了光纤干涉型传感器的结构及其原理,并对各种干涉型传感器的相位调制与解调技术的优缺点进行了分析。

关 键 词:光纤干涉型传感器  相位解调  零差法  外差法

Abstract:Fiber optic interferometric sensor can measure the signals through the demodulation of phase since the external signal imposing on the interferometer will induce the phase change of interference signal . In this paper the structure and principle of several kinds of optic interferometric sensors are introduced and the advantages and disadvantages of their phase modulation and demodulation techniques are also evaluated.
Keywords:fiber optic interferometric sensor  phase demodulation  homodyne  heterodyne
