Abstract

An optical intrusion‐detection sensor based on a Sagnac interferometer has been developed for fence‐mounted perimeter security applications. The interferometer is completely made of polarization maintaining fiber and related components. This sensor has been adopted by some important institutions as part of their physical security systems.
