An array of fibre optic seismic intruder detection sensors has recently been tested by QinetiQ. The array consisted of a set of distributed cable sensors and accelerometers, each being interrogated by an interferometric effect. Both types of sensor were able to detect a person crossing over the array, and frequency analysis of the signals suggests ways in which automatic intruder detection could be achieved.
