Abstract
Perimeter protection and intrusion detection systems and methods have become essential
parts of most security and surveillance systems. From applications, such as border
protection, through airport security, to equipment protection in vital plants, and so on,
perimeter intrusion detection systems (PIDS) have penetrated a significantly large number
of verticals. Of the core detection technologies that are currently used in these PIDS systems;
taut wire, vibration sensors, microphonic sensors, microwave sensors, seismic sensors, and
so on, have been the traditional solutions. However, optical fiber-based PIDS have gained
popularity, being fully passive systems that may not require power supplies or electronics in
the field, and having electromagnetic field immunity. In this seminar, an Fiber Bragg
Grating (FBG) based PIDS will be presented. This new invention offers all-weather
surveillance and instantaneous reporting of intrusions on perimeter fencing of critical
facilities. It also overcomes the limitations of other solutions that give low reliability of
detection and very high false alarm rate. It’s performance has been verified during
deployment by users like Singapore Changi airport who uses this technology as a primary
defence, allowing the security forces to be deployed effectively to respond to an intrusion.

Hao Jianzhong, received Ph.D in Fiber Optic Sensors from Nanyang Technological
University, Singapore in 2001, and M.Eng. and B.Eng. from Huazhong University of
Science and Technology in 1993 and 1990 respectively. She joined Yangtze Optical Fiber
Communication and Industrial Group, Wuhan, China from 1993 to 1995. Later she joined
Fujikura Technology Singapore, leading a team to embark design and development of hybrid
optical WDM and Isolator. Currently she is a principal investigator at Institute for Infocomm
Research (I2R), A*STAR, Singapore. She has secured more than SGD2.7 million cash
funding from various industries including a multi-million dollar project from Airbus. She
has published more than 70 papers in prestigious international journals and conferences and
filed four international patents in which two have been granted. Her research interests
include fiber optics sensors, Bio-Photonics, sensor packaging, and system integration.
