23 September 2005 Fiber optic sensors for perimeter security with intruder localisation
Author Affiliations +
Fibre optic have been using in security technology for 25 years. It started from simple systems where an alarm was generated only when a fibre (placed inside a fence, a net or a wire) was cut or broken. Now, there is a growing interest in research of sensors for disturbance localization. These sensors can be specially useful for perimeter security. In comparison with other sensors, they are passive, multikilometer-long devices and can be sensitive to variety of parameters. The fiber optic sensors with intruder localisation can be divided into three classes, that base on: interferometers, internal modes interference and Brillion scattering. In this paper, we will present our research of interferometer-based sensors as well as state of art of the other sensors.
