We describe an optical fiber interferometric sensor addressing technique which utilizes frequency modulation of a single laser source to control the visibility of individual sensors. Interrogation of the sensors is performed by matching the laser modulation frequency to the frequency response characteristics of each individual sensor. We show that improvements in system performance can be achieved through the use of pseudo-noise RF modulation applied to the laser.
