Hyperspectral imaging as a technique for investigating the effect of consolidating materials on wood
The focus of this study was to investigate the potential of hyperspectral imaging (HSI) in the monitoring
of commercial consolidant products applied on wood samples. Poplar (Populus spp.) and walnut (Juglans
Regia L.) were chosen for the consolidant application. Both traditional and innovative products were selected,
based on acrylic, epoxy, and aliphatic compounds. Wood samples were stressed by freeze/thaw cycles in order
to cause material degradation without the loss of wood components. Then the consolidant was applied under
vacuum. The samples were finally artificially aged for 168 h in a solar box chamber. The samples were acquired
in the short wave infrared (1000 to 2500 nm) range by SISUChema XLâ„¢device (Specim, Finland) after 168 h of
irradiation. As comparison, color measurement was also used as an economic, simple, and noninvasive technique
to evaluate the deterioration and consolidation effects on wood. All data were then processed adopting a
chemometric approach finalized to define correlation models, HSI based, between consolidating materials, wood
species, and short-time aging effects
