Multiplexing Fiber Bragg Grating Sensor System Based on Heterodyne Method

摘要：

Combining MATLAB/SIMULINK modeling and the existing designs, the system focusing on heterodyne modulation was established based on the feasible analysis of demodulation by Optical Frequency Domain Reflectometry (OFDR) and Wave Division Multiplexing (WDM). The simulation system with voltage control oscillator, triangular wave generator, light intensity modulator, multiplier, adjustable fiber F-P filter and adjustable Band-Pass Filter (BPF) was built up by Frequency Modulated Continuous Wave (FMCW) technology of radar signals demodulation. And the parameters were obtained from the simulation for further experiment.
