摘要：The addressing principle of distributed optical fiber Bragg grating (FBG) sensor based on frequency modulation continuous wave (FMCW) multiplexing technology was studied, and the theoretical analysis of FBG multiplex distance were carried out; In order to analyze the impact on the spectrum signal, the effect of grating position information, scanning time and scanning frequency range on the spectrum signals were analyzed by simulation. When the FBG multiplex distance is integer or non-integer multiple of system minimum resolution distance, for the FMCW multiplexing scheme was simulated. The grating distance, the scan time and the scanning frequency range significantly affect the signal strength and the signal-to-noise ratio. Finally, the related experimental system was established and the results are consistent with the theory.
