Two-mode fiber sensors based on elliptical-core fiber are of interest in a variety of strain sensing applications particularly in embedded fiber sensor systems. In recent papers we have reported passive interrogation techniques for such sensors configured in a lead-insensitive mode of operation. In this paper, we describe a time division multiplexed array of two-mode elliptical-core fiber sensors, based on the use of reflectometric sensor elements and passive laser FM based phase shift interrogation. Results obtained with a 4 channel system are presented.
