An overview of terahertz (THz) technology for the wood products industry is presented. The basic application areas that are amenable to exploiting emerging THz technology are examined. In doing so, the basics of wood structure are presented so that THz–wood interactions can be discussed. This will set the context for discussing a THz scanner that was deployed in a successful pilot study in 2008, which measured oriented strand board (OSB) mat density in the production process, and allowed mill operators to adjust the process based on real-time feedback provided by the THz scanner.
