Fiber grating matching demodulation system based on single chip microcomputer

通过对光纤光栅匹配解调原理的研究,将AT89S52作为核心处理芯片,提出了一种基于单片机技术的光纤布喇格光栅(FiberBraggGrating,简称FBG)匹配解调系统。利用曲线拟合的方法对步进电机步数与波长偏移量的数据进行拟合计算,确定波长微小偏移量,实现光纤光栅解调的目的。给出了该方案软硬件设计,并对解调系统的发展前景进行了概述。

A research of the principle of fiber grating matching demodulation system based on AT89S52 as core processing chip is presented. Using the synthetics curve of the steps of the motor and wave lengths of the FBG to calculate the tiny offset of wave length, achieving the intention of fiber grating and get the variable of detected object. The design of hardware and software are given and summarizes the foreground of the demodulation system.
