Wood X-ray inspection

X-ray inspection systems are used for inspection both of logs and sawn timber.

Logs can be inspected using X-ray linescan or CT methods.

LINX detectors of typically 1 metre length are used to detect the X-rays after passing through the logs.

The use of multiple X-ray sources and detectors enables many parameters of a log to be measured, including knot volume, ring width, rot and density. This permits much more efficient use of material.

Thicker logs require higher X-ray energies.

Different scintillators can be fitted to optimize detector perfomance for X-ray energies between 100keV and 225keV.

Sawn timber is inspected by a single X-ray source and by a smaller detector, typically 0.5m long and provides measurement of timber thickness and quality.
