In this paper, a self-consistent inverse procedure is developed for the estimation of linear
thermal expansion coefficient and thermal diffusivity of solids from transmission
photoacoustic measurement. This procedure consists of two single-parameter fitting
processes applied alternately: phase data are fitted by shifting thermal diffusion coefficient,
while amplitude data are fitted by shifting thermal expansion coefficient. Each fitting process
uses the resulting parameter of the other, previously finished one, thus converging to the …
