New fibre-optic device to detect explosives

Australian researchers have created a device that may help in the fight against terrorism.

The optical-fibre sensor uses light and glass fibres to detect trace amounts of explosives – as little as 6.3 parts per million.

Current explosive-detection devices work by identifying metal casing which usually holds explosives. But the team leader, Dr Georgios Tsiminis, said the rise in homemade explosives, which may not be encased in metal, made this problematic.
