abstract = "In transmission gas-microphone photoacoustics, in order to protect the microphone and improve the Signal to Noise Ratio of the experiment, a thin non-transparent layer is applied on the surface of the sample. When the applied layer is not illuminated – the incident light is passed through the sample, instead, and all the transmitted radiation is absorbed at the non-illuminated side of the system – optical absorption properties of the sample are preserved in the recorded photoacoustic response [1-3]. Thermoelastic component of photoacoustic response is based on the integral of temperature distribution in the sample. However, in the described configuration, the amplitude ratio and the phase difference of surface temperature variations can notably influence the direction and the intensity of the thermoelastic movement of the sample, thus modifying the induced photoacoustic response. Herein, the analysis of surface temperature variations is done, aimed at the prediction of thermoelastic component of the induced photoacoustic response, and the sensitivity of the described model to the alterations of optical absorption coefficient is analyzed and discussed.",
