AP Sensing’s Director of Research, Dr. Gareth Lees, collaborated on a Laser Focus World article titled “Smart fiber-optic sensing systems enhance physical border walls and fences.”
If you want to monitor physical borders, such as walls and fences, a fiber-optic sensing system is ideal as they enable you to measure sound, movement or temperature – continuously and in real-time – along with long structures.
For remote borders with little or no infrastructure, there are various techniques that can keep an eye, or rather an ear, out. QinetiQ, a British firm, has a system called OptaSense, which uses a fiber-optic cable laid in the ground. Sound from above creates vibrations in this cable.
Dr. Chris Minto, Engineering Director of member company OptaSense, will present “Towards 1 Billion Sensors: Distributed Fiber Sensing as a Pervasive IoT Contributor” on behalf of FOSA during this week’s Optical Networking and Communication Conference (OFC) in San Diego, California.
Fiber optic sensing technology converts cables installed alongside transport infrastructure, such as railroads or highways, into an array of thousands of sensors which can detect acoustics, temperature or strain signals by using optical sensing techniques.
