ABSTRACT:
Bi-directional (longitudinal and angular) three-dimensional volumetric microwave scanning of a whole roll or pallet of paper (FIGS.3, 4), including three-dimensional volumetric mapping of internal properties and characteristics (moisture content, density, material uniformity, defects and types thereof, and variabilities thereof) of the roll or pallet of paper. Transmitted microwaves propagate through longitudinally and angularly defined portions of individual cross-sectional volumetric segments of the roll or pallet of paper. Microwave parameters (amplitude, phase) are perturbed by, and are a function of the internal properties and characteristics of, the contents of volumetric segment portions of the roll or pallet of paper. Microwave differential parameters (amplitude attenuation, phase shift) are calculated and used for calculating and determining values, relationships, two-dimensional graphs and maps, and, three-dimensional volumetric graphs and maps (FIGS.5, 6), of the internal properties and characteristics of at least part of the roll or pallet of paper.
