20.500.12556/DKUM-38170 DOLOČANJE EMISIVNOSTI ZA POTREBE TERMOGRAFSKIH PREISKAV ESTIMATION OF EMISSIVITY FOR THERMAL INVESTIGATION Termokamera, imenovana tudi IR kamera, je namenjena prikazu temperaturnih porazdelitev na površini materiala. Za natančnost meritev je zelo pomembna pravilna izbira koeficienta emisivnosti, vezana na material objekta, ki ga opazujemo. V delu so tako predstavljene teoretične osnove termografije in podane fizikalne osnove sevanja teles, kar med drugim zajema tudi definiranje emisivnosti, emisivnosti črnega telesa ter koeficiente emisivnosti za posamezne materiale. V nalogi je opisano tudi delovanje termokamere. Predstavljeni so možni načini določanja emisivnosti ter vplivi okolice na točnost meritev. Thermal imaging camera, usually named IR camera, is used to present the thermal distribution on the surface of the material. Choosing the correct emissivity for the material of the observed object is very important for precise measurement. Theoretical thermography basics are presented in this thesis, in addition to physical basics of body radiation. Furthermore, the factor of emissivity and emissivity of blackbody are described. Moreover, emissivity for different materials is presented in this thesis. It also contains working principles of IR camera. Possible methods of estimation of emissivity and surrounding influence on the precision of measurement are described. termografija termokamera emisivnost določanje emisivnosti thermography thermal imaging camera emissivity estimation of emissivity true true false [J.
