The operation of the far-infrared radiator was controlled through the temperature of the drying medium (air or superheated steam) measured at 30 mm above the sample surface via the use of a Proportional¨CIntegral¨C Derivative (PID) controller (Shinko, JCS-33A-R/M, Osaka, Japan) with an accuracy of ¡À0.1 C. |

ÔÙÇóÖúһϣºProjections (assembling of transmitted beams) are recorded for several angular positions by rotating the sample between 0 and 180. Then, a back-projection algorithm is used to reconstruct 2D or 3D images, depending on the method used. In the case of 2D images each pixel has a grey level value corresponding to the local attenuation coefficient. |
