Abstract :
The basic principles of Frequency Modulated Continuous Wave (FMCW) multiplexing technique addressing the distributed fiber Bragg grating (FBG) sensors were studied, and the theoretical analysis of FBG multiplex distance were carried out; In order to analyze the impact on the spectrum signal, when the FBG multiplex distance is integer or non-integer multiple of system minimum resolution distance, for the FMCW multiplexing scheme was simulated. Finally, the related experimental system was established and the results are consistent with the theory.
