Paper Abstract

Optical low coherence reflectometry (OLCR) was used for the measurement of the local fiber Bragg grating (FBG) birefringence. The birefringence with resolution of 4μ10-6 was determined directly from oscillations in the OLCR amplitude with a spatial resolution on the millimeter scale. Using OLCR phase in combination with inverse scattering algorithm the birefringence was retrieved with a high spatial resolution of 25 microns. The technique using OLCR amplitude was applied for measuring birefringence of a FBG under diametric loading.
