Abstract

Water has an absorption band of four wavelengths, namely 1.2, 1.45, 1.94, and 2.94 micrometers, in the near-infrared light range. When a sample is irradiated with light of the above wavelengths, this sample will absorb light in accordance with its moisture content. As moisture content of wheat increased, reflectance from the wheat sample decreased, which indicates that water is a strong light absorber than a sandy wheat sample. When light hits a sample, several interactions can occur: specular reflectance, diffuse reflectance, absorption, transmittance, refraction and scattering. In this paper we try to find out influence of several interactions on accurate measurement for moisture wheat
