Paper Abstract

An optical fiber sensor system for location of a vibrational disturbance along the fiber is presented. The sensor system is based on a serial array of identical F-P interferometers, formed directly in the single mode SMF-28e fiber by pairs of fiber Bragg gratings with reflectivity of 0.04 % each. Interferometers were interrogated by a DFB diode laser which was intensity modulated at 10 kHz. A method for localization of a disturbed interferometer and experimental results for a serial array of 14 sensors are presented. Simple sensor configuration and the use of low-frequency components make it potentially inexpensive and suitable for applications where a continuous monitoring of long structures has to be performed for appearance of vibrations.
