In December 2004, using our new hybrid scanner, we achieved, for the first time, 28 micron¹ scans. This is equivalent to 907 scan points per inch, or 36 points per millimeter. This is almost 4 times sharper than the densest sampling rate, 100 microns, of currently available 3D surface scanners capable of scanning objects the size of cuneiform tablets.

The images to the left are screen shots of 3D renderings of a single cuneiform sign, the dingir sign, from 3D surface scans taken at different resolutions.

(For more information on this particular tablet see the iClay web page.)
