AB  - In order to make the photothermal effect detectable from a sample with low optical absorption, an optically opaque layer must be applied on its surface. A model of optically induced temperature variations for such a structure is derived, with a very thin coating applied on the non-illuminated (back) side of the sample and neglecting heat flux dissipation in the coating. Validation of the model is performed by comparing the obtained results with the results for the corresponding two-layer structure model. The influence of optical absorption on surface temperature variations of both optically transparent and semi-transparent film, whether the film is a good or poor thermal conductor, is analyzed. It is shown that the effects of optical absorption in the coated structure can be observed through variations in the measured temperature, despite the low absorbance of the sample.

AB  - U ovom radu ispitivan je uticaj nanetog sloja boje na površinske temperaturske varijacije uzorka poliamida. Uzorak, dobijen laserskim sinterovanjem industrijskog praha PA2200, se obasjava mnodulisanim laserskim snopom, dok se naneti sloj boje ne pobuđuje direktno. Razmatra se dinamička komponenta temperaturske promene na površini uzorka u transmisionoj i refleksionoj konfiguraciji, kao ključna komponenta formiranja fotoaksutičkog odziva.
AB  - In this paper, the influence of the applied dye layer on surface temperature variations of polyamide sampleis investigated. The sample, obtained by laser sintering of PA2200 industrial powder, is irradiated by a modulated laser beam, while the applied layer is not excited directly. Dynamic component of temperature change at sample surface is considered, in both transmission and reflexion configuration, as the key componetn in the formation of photoacoustic resopnse.

AB  - 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.
AB  - 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.

AB  - Specijalno pripremeljeni PLLA uzorci su prekriveni tankim polimernim slojem akrilne boje, formirajući na taj način neprozirni zaštitni sloj. Uniformnost i debljina nanetog sloja su potvrđeni, a onda su izvršena merenja frekventnog fotoakustičkog (FA) odziva dobijenog dvoslojnog sistema korišćenjem FA ćelije minimalne zapremine u transmisionoj konfiguraciji. Ponovljivost je potvrđena višestrukim merenjima na dva nivoa debljine i za svaku stranu pojedinačno. Prikazani rezultati obrađenih merenja potvrđuju ispravnost odluke da se u teorijskom modelovanju odziva i potonjoj interpretaciji koristi dvoslojni generalizovani model FA odziva. Predložene su dalje metode obrade dobijenih podataka, sa ciljem kvantitativne karakterizacije ispitivanog polimernom materijala pomoću procedura zasnovanih na veštačkoj inteligenciji (neuronskim mrežama).
