Specimen orientation for the calibration of direct scanning X-ray wood densitometers.

摘要

It was found that specimen orientation has considerable effect on the calibration of direct scanning X-ray wood densitometers. A comparison between various orientations was made and verified by a test on Larix olgensis wood samples. Optimum calibration is accomplished when the specimens are made in such a way that the radiation beam is passed through the wood in the tangential direction and scans it in the radial direction.
