Abstract

The results are presented which form the basis against which the technique of photoacoustic PA diagnostics of inhomogeneous liquid samples can be developed. Usually, a thin-layer small-volume inhomogeneous probe presents a considerable challenge for diagnostics. The paper shows that gas-microphone PA technique works well here, and moreover it presents an added bonus if the thickness of the layer is close to the dimensions of immersed inhomogeneities.
