“…Devices tested for RPW detection in date palm, including digital and thermal cameras, TreeRadarUnit™ (TRU) (Radar 2000, Radar 900), resistograph, magnetic DNA biosensor, and NIRS have been used for decades to detect anomalies in plants caused by biotic or abiotic stresses (Halabe et al, 2009, Li et al, 2018, Fracchiolla et al, 2013, Pallav et al, 2009). In the present study, the accuracy of digital and thermal cameras was around 50 to 60%, whereas visual detection was 87%.…”

“…This innovative technology is commonly used in arboriculture to observe the internal status of woody plants. Resistographs are reliable devices used to detect decay and cavities in woody trees (Butnor et al, 2009, Halabe et al, 2009, Li et al, 2018). It comprises a micro drill that is introduced horizontally into the trunk and the variation in resistance in the wood is depicted into a graph.…”

“…Halabe et al showed that GPR can be used to accurately identify subsurface defects such as knots, decay, and metallic nails inside logs that were not visible from outside observations. Combining the use of dielectric properties and the threshold method, the depth error detected at the sawmill was approximately 10% [22]. Lin et al reported a 17.78-52.61% error in the tree trunk decay area using a two-dimensional stress wave method for detection [23].…”

“…Studies pointed out that these anomalies could be associated the inner discontinuities between the bark and the internal trunk and lower velocities correspond to living trees, while higher velocities are associated with timber [5]. Other studies located the position of internal defects and the algorithm for identifying the defects in wooden logs using GPR [6]; some others showed relations between relative permittivity and moisture content of the different wood samples [7]. In addition, some make evaluation of wood beams in buildings based on GPR [7][8].…”
