Abstract

The operation of new quasi-distributed interferometric sensor is discussed. The sensor is based on the array of unbalanced interferometers formed by point polarization couplers along birefringent fiber. Simultaneous interrogation of the sensing interferometers was achieved by using spectroscopic methods and a simple signal processing. Results of investigation of sensor performance and analysis of cross-talk problem are presented.
