A CT system for the analysis of prehistoric ice cores
S.259-270 The task was to measure ice cores with a diameter of 10 cm and a length of 1 m that were drilled out of Arctic and Antarctic glaciers down to 3,000 m depth. By means of computed tomography (CT), pieces of 1 m length are measured and three-dimensional volume data with high spatial resolutio...
