Abstract

The use of submillimetre (SMM) waves for non destructive testing of paper has already been demonstrated. This report presents the basic results wich led to the use of SMM waves to monitor the fibre orientation anisotropy in paper. The measurement of moisture content and basis weight is also covered. An experiment to test the effect of moisture content on the polarizing properties of paper is presented. Measures were made for three wavelengths (70, 96 and 118 microns) and for moisture content covering the region 0 to 40 %. The effect of bound water to cellulose surface will be introduced to explain the results.
