Fiber Bragg Grating Sensor Multiplexing System Based on FMCW

Abstract:

The addressing principle of distributed optical fiber Bragg grating (FBG) sensor based on frequency modulation continuous wave (FMCW) multiplexing technology was studied. The effect of grating position information, scanning time and scanning frequency range on the spectrum signals was analyzed by simulation. The FMCW multiplexing system, which was composed of the arbitrary waveform generator, light intensity modulator and multiplier etc, was established and the certifications were delivered by the experimental system.
