Radio frequency sensors to detect internal and external wood defect

The Radio Frequency (RF) sensor is a new kind of scanner for wood defect detection developed by CEO during the PINOCCHIO Project. The Radio Frequency inspection is the technique by which the wood scanner works and produces density maps of both surfaces in real time. A European patent was applied for the RF scanner because of the highly innovative procedure utilised, which overcomes the disadvantages of conventional methods. More particularly, this kind of sensor is able to produce wood density maps of both surfaces thus to detect defects. The device provides a non-invasive investigation and methods capable of not being influenced by dust or dirty on timber surfaces neither to spots nor timber grading. The RF scanner can work in real time that is at the speed required by the wood industry. Not only it can detect the outer defects but also the internal ones (even 1-2 mm deep). For wood inner inspection, the RF scanner can substitute the present systems operating with X rays, which are not safety for men. The RF system is mainly useful for dielectric material such as wood.
