Abstract

The model layered system of thin olive oil layers spread on the water surface was studied using a photoacoustic method. Dramatic changes in the signal phase and rather slight variations in the signal amplitude were observed in reference to the oil-water interface probing. Applying a principal relation of the depth profiling approach between the thermal diffusion length and thermal diffusivity the latter for a particular layer thickness 25 micrometers , was evaluated to be 1.22 by 10^-3/s being a characteristic value for kind of oils examined.
