“…Speckle pattern analysis, as implemented by Rowe [16], can also be used as a technique for fence mounted intruder detection. Choi [68], Arnaoudov et al [69], and Kwon et al [70] all report similar perimeter fence sensing systems based on this technique. The method uses MM fiber that produces a speckled pattern when light is launched into it.…”

“…All three groups reported effective results although each of their systems required extensive signal processing to remove external noise caused by the environment. Arnaoudov et al [69] facilitate the signal processing using a microcontroller and produced a relatively simple hand held sensor module, whereas Kwon et al [70] use a PC based system running a National Instruments LabVIEW program for signal processing.…”

Fiber optic sensors have become a mainstream sensing technology within a large array of applications due to their inherent benefits. They are now used significantly in structural health monitoring, and are an essential solution for monitoring harsh environments. Since their first development over thirty years ago, they have also found promise in security applications. This paper reviews all of the optical fiber based techniques used in physical intrusion detection systems. It details the different approaches used for sensing, interrogation and networking, by research groups, attempting to secure both commercial and residential premises from physical security breaches. The advantages and disadvantages of the systems are discussed and each of the different perimeter protection methods are outlined, namely, in-ground, perimeter fence, and window and door protection. The study reviews the progress in optical fiber based intrusion detection techniques from the past through to current state-of-the-art systems and identifies areas which may provide opportunities for improvement, as well as proposing future directions in this field.

“…We extend here the previous study [10] of a hand-held fiber-optic perimeter sensor that uses low-cost conventional components and allows flexibility for a variety of applications. We use selective mode excitation, a number of decision criteria such as a signal threshold and temporal sequence of time differentiated signal pulses to discriminate between slow-and fast-varying signals as well as all-fiber spatial filtering that is polarizationsensitive.…”
