Abstract

The time-division multiplexing of polarization-insensitive fiber optic Michelson interferometric sensors (TDM-PIFOMI) with compensating interferometer is presented. The crosstalk of lead fiber in a general time-division multiplexing of the fiber optic interferometric sensors is described and demonstrated. The experimental results match excellently with theoretical derivation. According to the experimental result and derived theory, only the induced phase signal of the sensitive lead fiber results in lead crosstalk , the sensing fiber of one sensor in the time-division multiplexing should not be placed on the effectively sensitive lead fiber of the other sensor to avoid the sensor crosstalk from lead crosstalk .
