Sažetak
By interaction of the component particles of any substance, molecules or atoms and electromagnetic radiation the result can be some complex motions and/or the position change of these particles within the observed substance. Together eith these motions the energy content of these particles i s being changed as a result of electromagnetic radiation. The energy changes are quantized and their amounts primarily depend on the motion type which prevails and then the translating, rotational, vibrational, electronic and nuclear energy levels can be taken into consideration. By radiation in NIR (Near InfraRed) region the particles are excited on symmetrical and asymmetrical stretching and curving and particles vibrate on elastic deformation. The particles own frequency vibration depends on their masses and strength of their mutual relation. These magnitudes are different for different groups of atoms and each group predominantly absorbs NIR radiation of the accurate specific wavelength which is characteristic for these atom groups. It has been established that the water molecules particularly absorb electromagnetic radiation with the wavelength of 1200, 1450, 1940 and 2950nm, and explicitly with the wavelength of 1450 and 1940nm. Thus those ones for water are called absorbing and on the basis of absorption with these wavelength the water content can be determined in thin foliaceous and granular substance structure. The creation of the transmissible infrared moisture meter, whose functioning is based on the above mentioned principles, is the research final goal in this paper.
