Interrogation system of the optical fiber Fabry Perot sensor based on tunable Fabry Perot filter

在光纤法珀(Fabry Perot,简称F—P)传感解调系统中,获取传感器反射信号的光谱成分是一种实用的方法,论文从可调谐珐珀滤波器波长选择特性的原理出发,提出使用可调谐珐珀滤波器获取传感器反射信号的光谱,从而实现光纤珐珀传感器的腔长信息解调,并在此基础上使用DSP为控制核心搭建了该系统,实验证明了方案的可行性。

In the optical fiber Fabry Pemt sensing system, the key of the Fabry - Pemt cavity length＇s interrogation is how to obtain sensor＇s spectrum. In this paper, based on the property of the tunable Fabry Pemt filter. A scheme of optical fiber Fabry Pemt sensor interrogation system is proposed; Setting up this system with the help of DSP. The result shows it is effective.
