Intensity modulation, induced by a modified microbending pressure sensor is considered as a possible transduction mechanism for detecting environmental changes. Implementations of these kind of sensors into multiple sensor systems is based on simple and reliable technology with multimode fiber, couplers, a reference and a multiplexing technique. A frequency domain technique is presented to interrogate unambiguously time division multiplexed sensors. Line neutrality is obtained by a referencing method. Torsion experiments with multimode fibers in a microbend pressure transducer application, to improve the sensor attenuation, are reported.
