G. S. C. Tree-Ring Scanning Densitometer and Data Acquisition System

Jones, F. W., Parker, M. L. 11 1900 (has links)
A tree-ring scanning densitometer and data acquisition system has been built by the Geological Survey of Canada to extract tree-ring density and tree-ring width data from dendrochronological specimens and X-ray negatives of specimens. The system produces tree-ring density plots, ring density and ring-width bar graphs, and printed and punch tape digital data. This prototype was built primarily from commercial pre-constructed electronic components, but a modified densitometer and other original-design units also were used in the construction.
