Abstract
A new approach for multiplexing interferometric fiber optic sensors
is described and studied. The approach is based on a lattice of unbalanced
Mach–Zehnder interferometers. This configuration is inherently low-loss
and can be implemented and deployed in a simple manner. The signals from the
cascaded sensors are extracted from the measured data via a layer peeling
algorithm. A fifth-order polarimetric implementation of the proposed multiplexing
technique has been constructed and characterized. The third sensor was buried
in a sandbox while the rest of the sensors were spooled on a bobbin. The system
successfully separated and monitored the pressure variations in the different
sensors with minor crosstalk.
