Abstract

This work presents the acquisition and processing of data for the detection of knots in solid wood samples. The data were obtained by means of a microwave system based on an emitter (frequency: 10.5 Ghz; power: 10 mW). A diode detector array was used to obtain a matrix of voltage data corresponding to each wood sample. The data collected for each wood sample were correlated using statistical variables; these data were saved and processed. The results of this treatment are shown as tomographic images and an improvement in the image resolution of the knots in comparison with a previous work was observed.
