Abstract
We propose and experimentally demonstrate a time-division-multiplexed
acoustic sensor array employing multiple low-gain Er-doped fiber amplifiers
to multiplex ten compact Fabry-Perot acoustic sensors. We show that the ten
sensors can be interrogated with a single laser diode at a single wavelength,
and exhibit the same measured SNR within
$\pm$
0.95 dB of each other. We present a model
to identify the dominant noise contributions, and their dependence on the
number of multiplexed sensors. This model predicts that more than 350 sensors
can be multiplexed with the proposed architecture.
