Detecting Defects of Leather Material on the Base of Radiometric Method in MM-Wave Band

Leather material blemish zone detection and registration of areas suitable for next utilization are actual tasks in leather manufacturing branch. Ultra-high frequency (UHF) radiometric method of leather material diagnostic should be applied as a prospective solution on this way. With the aim of radiometric method potential abilities evaluation in leather materials diagnostic, a set of laboratory measurements of radiothermal radiation total loss factor was realized in microwave and millimeter wave bands for prime product of leather material, which is ordinarily obtained in the initial stage of cattle skin treatment. It is possible to declare that radiation optimal wavelength, which will be correlated with maximum brightness contrasts between defect and condition areas in inspecting leather material will be gradually drifted towards to shorter millimeter wavelength for observed diagnostic method.
