Paper Abstract

In the first part of this paper optical fibers and fiber based devices frequently used in sensor systems are presented. These are fibers with high and low birefringence, polarizing fibers, in-fiber Bragg gratings, polarization preserving fiber-optic couplers, and in-fiber phase modulators. In the second part the most popular sensing mechanisms are reviewed. This review covers intensity modulated sensors based on microbending or absorption losses, difference types of interferometric sensors, and fiber-optic gyros. Finally, the concept of distributed sensors allowing measurement of 1D distribution of a specific physical parameter are presented.
