Dendroscan

"DendroScan is a system developed for measuring tree-ring width and density. The DendroScan system enables the user to measure both tree-ring width and density or just ring widths. The system can use prepared wood samples (for ring widths only) or X-ray images. DendroScan is fully described, with discussion of sample preparation, calibration procedures, and data analysis. Information and instructions for the user are included. The DendroScan program is enclosed on a DOS-formatted disk, along with a precalibrated precision wedge for converting X-ray images to density. The system is precise and accurate, yet inexpensive and composed of readily available parts."--Jacket.
