| Abstract: | 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. |
