Technological spin-outs from universities are usually expected to emerge from the engineering department, the school of medicine or the faculty of physics. At Oxford, however, they like to do things differently. The latest invention to emerge from the dreaming spires of England's oldest university is the brainchild not of any of these academic Johnny-come-latelies, but rather of a group who trace their origins to Oxford's medieval foundation: its classicists. The multispectral-imaging scanner developed in the faculty of classics by Dirk Obbink, a lecturer in papyrology and Greek literature, and Alexander Kovalchuk, a mathematician and physicist, is able to detect traces of faded or hidden inks and paints in historical manuscripts, expose forged documents and art works, and highlight forensic evidence such as fingerprints and stains from bodily fluids. It will soon be available commercially from a firm called Oxford Multi Spectral. Multispectral imaging works by scanning objects at a series of specific frequencies both within and beyond the visible spectrum. It is able to highlight details human eyes cannot normally see, either because they are swamped by the signal from other visible frequencies, or because they are not detectable by the rod and cone cells of the retina.
