This paper presents the model of surface temperature variations, resulting from the photothermal effect induced in a “thin film – highly absorbing surface layer” structure, where the thin film is irradiated. The influence of the optical absorption coefficient and sample thickness on the induced temperature gradient is analyzed. It is shown that, depending on the product of these parameters (optical absorbance) in the described structure, the phenomenon of inverse temperature gradient can occur, further influencing the direction and the magnitude of thermoelastic displacement.
U radu je prikazan model koji opisuje površinske temperaturske varijacije nastale kao posledica fototermalnog efekta u strukturi tanki film – prevlaka sa visokim koeficijentom optičke apsorpcije, gde je obasjan tanki film. Analiziran je uticaj koeficijenta optičke apsorpcije i debljine uzorka na indukovani gradijent temperature. Pokazano je da u zavisnosti od proizvoda koeficijenta optičke apsorpcije i debljine uzorka (apsorbanse uzorka), u takvoj strukturi može doći do formiranja inverznog temperaturskog gradijenta, što utiče na smer i veličinu termoelastičnog pomeraja.
