Temperature distribution formulae-applications in photoacoustics

M. Maliński
Department of Electronics - Technical University of Koszalin

This paper presents the new formula for the distribution of
a periodical component of the temperature in the samples excited by the
periodically modulated beam of light. It was shown that this formula enables the
piezoelectric photoacoustic spectra analysis and interpretations. The influence
of the backing material on the temperature distributions in the sample and
piezoelectric photoacoustic spectra was presented and analyzed.
