BBC News has an interesting segment on how digital technology is changing the field of archaeology:
Archaeologists may not need to get their hands so dirty any more, thanks to the kind of digital technology being pioneered at Southampton University.
Its ‘µ-VIS Centre for Computed Tomography’ possesses the largest, high energy scanner of its kind in Europe: a ‘micro-CT’ machine manufactured by Nikon.
Capable of resolutions better than 0.1mm — the diameter of a human hair — it allows archaeologists to carefully examine material while still encased in soil.
Using visualisation software, archaeologists can then analyse their finds in 3D. This keeps the material in its original form, and postpones any commitment to the painstaking process of excavation by hand.
