Timber materials are widely used in various industries; from construction to furniture manufacturing. One of the critical factors affecting the structural integrity and longevity of timber is water loss-induced damage; which often occurs under low-temperature stress conditions. This study explores the application of robotic-based terahertz spectroscopy imaging as a non-destructive and efficient technique for assessing the impact of water loss on timber materials under low-temperature stress. Moisture level evolution in various timber species was experimentally investigated by performing frequency modulated continuous wave terahertz spectroscopy and using a six-DOF (degree-of-freedom) robotic arm. The reflected signals were analyzed to compute the corresponding dielectric property reference value at different moisture content levels through signal processing in the time and frequency domains. The effect of fibre direction and moisture content on THz waves was performed and the validity of frequency modulated continuous wave terahertz spectroscopy for effective; was discussed. © 2024; NDT. net GmbH and Co.
