基于FBG传感器多波长解调检测设计
|
摘要
光纤光栅解调系统的成本通常占整个传感系统成本的绝大部分,它的检测精度也往往决定着整个系统的传感精度。目前,由于波长编码信号解调检测困难而造成系统成本过高,在普通领域难以接受。提出了用一个可调F-P滤波器同时解调检测多个光纤光栅的方案,对其主要数值结论进行了分析讨论。
Fiber Bragg Grating demodulation system costs usually account for the entire cost of the vast majority of sensor system, it also often determine the accuracy of the entire system of sensor accuracy. At present, because the wavelength detection coding signal demodulation system difficulties resulting high cost in the general fields unacceptable. In this paper, using an adjustable FP filter at the same time demodulation of a number of Fiber Bragg Grating programme, its main numerical conclusions were discussed.
