Abstract :
The transmission readout of a dual-mode single-fiber frequency-modulated continuous-wave (FMCW) distributed sensor presents parasitic beat signals when more than one transducer is activated at a time. Experimental evidence of this effect is shown, and a solution for multipoint operation is proposed. This solution is based on the nature of the two types of interference occurring at the fiber end
