"New technology developed by Oxford University’s classics department could help reveal the secrets of historical documents. A spin-out firm is commercialising the scanning device, which uses different wavelengths of light to detect faded or erased ink, for analysing manuscripts and archived documents, as well as modern forgeries. ‘The technical leaps we made mean many ancient documents that were previously unreadable can now be scanned and read,’ said Dr Dirk Obbink, head of the research group that developed the scanner."
