A technology company has claimed a breakthough which could revolutionise airport security and bomb detection.
The technology aims to improve security checks
Cascade Technologies said testing on sensor technology had shown the potential to "fingerprint" explosives in a few milliseconds.
The Stirling-based company said airport security staff could be using hand-held detectors within two years if it wins more funding for the project.
It is hoping to receive government support to push the idea forward.
The technology is based on a laser-based sensor which is capable of detecting explosives and may also detect whether people had recently handled home-made explosives.
The company, based at Stirling Innovation Park, claimed the fingerprinting system could take the form of a hand-held portable screening unit for use in airport carousels, post rooms and check points.
Cascade Technologies chief executive John Fuller said: "The technology is at a critical stage and prototype studies have shown that the instantaneous fingerprinting of explosive compounds is possible."
Mr Fuller said the company had received "significant" private investment, adding: "The US government has invested about £21m in similar projects and £9.6bn in total on airport security alone.
"Cascade has had a five figure sum from central government to help demonstrate the technology."
