Examination of power poles by computerized tomography
IRG/WP 2142
J A Taylor, I L Morgan, H Ellinger
The technique known as computed axial tomography (CAT or CT) has become widely known because of the success it has achieved in medical imaging and diagnostics. It has now been used to give non-destructive crosssectional pictures of a variety of industrial objects, including wooden power poles, with a spatial resolution of about 1 mm (0.04 in.). It is obvious the benefits that would be derived from being able to locate and determine the location and extent of knots, surface checks, internal cracks or rot and penetration of preservative. The internal density and possibly straightness of grain may also be assessed.
