Abstract :
A transmissive serial array architecture for multiplexed interferometric fiber-optic sensors based on time division addressing is discussed. The configuration gives rise to intrinsic optical crosstalk between sensor elements of the system due to multiple cross-coupling of pulses between the series of sensor elements and the output fiber bus. This crosstalk is theoretically analyzed in detail, and compared to experimental results obtained with both three- and eight-sensor networks. Phase detection sensitivities as low as approximately 10 mu rad/ square root Hz at a signal frequency of 1 kHz are reported.<>
